Solar Panels | Solar Modules

Everywhere you look, solar panels are gaining ground. In various regions of the globe thanks to naturally sunny weather, it’s no wonder why more and more people make the investment. In addition to the affordability factor and the big drop in component prices, there is also the matter of saving money energy-wise.

But isn’t the whole installation process a complicated one? And what makes one panel more special than the other?

Apart from providing every customer with the best possible solar panels the market has to offer, we also pride ourselves on keeping people informed. Here are some quick facts, considerations and features about solar, to get you started.

What is a Solar Panel?

Solar panels are made up of silicone cells, which is the magic component for turning sun-rays into energy. Some panels will have a single, solid silicone cell (monocrystalline), while others will have pieces of silicone that have been melted together (polycrystalline). These cells are then fixed inside a frame, and covered with a protective glass.

When the panel is properly angled, it will capture sun-rays and convert it into DC energy. In turn, the DC energy gets converted to AC energy via an inverter, which you can use inside the home for your loads. (tv, fridge, lighting, etc)

Types of Solar Panels

The panels are classified into three classes: mono-crystalline (single crystal), poly-crystalline (multiple crystals), or amorphous silicon.

Mono-crystalline Modules

Mono-crystalline is indicative of the continuous and unbroken sample of silicon in which the cell is manufactured from. This method uses very pure silicon grown in a complex growth process, and then sliced into wafers that compose the individual cells. This was the first method used to manufacture solar cells, and are still highly regarded for their efficiency ratios.

Poly-crystalline Modules

Poly-crystalline panels are composed of many crystallites of varying size and orientation. These multi-crystalline panels are generally less expensive and slightly less efficient than mono-crystalline modules, yet lately the difference in efficiency is very small. Like their mono-crystalline counterpart, the cells are also cut into wafers that make up the individual cells of a solar panel.

Thin Film Modules (Amorphous)

Amorphous solar panels use the non-crystalline, allotropic form of silicon, in which a thin layer of this silicon substrate is applied to the back of a plate of glass. These panels are much cheaper and less energy efficient, yet they are more versatile in how they can be used. For example, amorphous solar panels can be manufactured into long sheets of roofing material. Thin Film solar panels also fall into the amorphous category. This type of cells can be mounted on a flexible backing, making them more suited for mobile applications.

What is the lifespan of a solar panel?

Each of the solar panel types is estimated to last at least twenty-five years. Instead of stopping production completely, electricity production will decline a little, gradually, over decades. The longevity of a solar panel refers to the number of years before the unit starts producing only 80 percent of its original power rating. The industry standard for warranties is 20 to 25 years, although it is not uncommon for panels to produce adequate power for over 30 years.

Up to 30 YEAR POWER GUARANTEE

ZEROhomebills.com solar manufacturers provide up 30 year power guarantee on the solar panels. We offer the longest power guarantee on the solar panel in the industry to assured our solar panels generation of energy, and also to assured you get the right return based on your investment.

Off-Grid Solar versus Grid Tied Solar

Solar panels are used extensively in rural areas, where access to the grid is non-existent or inaccessible. These installations are called off grid (or independent, stand-alone, island) solar power systems, and require the use of batteries to store the energy for use at night or on long stretches of overcast weather.

The energy stored in the batteries leaves the batteries as DC electricity which can power DC appliances (as in RV’s) or be converted to alternating current (AC) for use with conventional appliances. Much like running your own mini utility company, this method gives you full independence from the national grid.

  • Grid Tied Solar

You can eliminate the cost of batteries by going with a system that connects right into your home’s main junction box and use the grid as your power source at night or on long stretches of inclement weather. These installations are known as grid-tied or grid-interconnected solar systems. This version of solar system enables you to sell any excess power you produce back to the utility companies who have chosen to support “net metering”. Once you are signed up on a net metering program, your utility company will have a smart meter installed known as a Time of Use Meter, which will actually run backwards when you are producing excess power.

It is wise to keep in mind that Grid tied systems without a battery backup, are only functional when the grid is operational. Due to anti-islanding features on grid tied inverters, which protect utility workers from working on a live line, grid-tied systems without a battery back up will not continue to produce power during a power outage regardless of whether you have sunshine or not.

  • Grid Tied Solar of course that needs to be connected …

Since solar panels produce DC, or direct current, they must be coupled with a solar inverter to convert the energy from DC to AC, or alternating current. In a grid tied system this can be done by a large central inverter, or each solar panel can be outfitted with its own micro inverter. Once the power is converted to alternating current and its phase is synchronized with that of the grid, it is then tied in to your main junction box, which is ultimately interconnected to the national grid.

What other components and equipment I need for a fully functional solar system?

  • Solar Inverter

The inverter has one specific purpose – to safely switch the DC energy from the solar panels to AC energy, which can be used inside the home. Without a solar inverter, you won’t be able to utilize the energy for your appliances or lights. Since the solar inverter is the heart of every solar system it’s logical that you want to invest in a quality inverter; given its critical place in the equation. You can find out more about solar inverters here.

  • Solar Batteries

Batteries are an optional components. There are people who use solar power on demand, which means they only use solar energy when the sun is shining. But it also means they don’t have solar power during the night. For the most part, when people install a solar array, they take the battery option as well. Provided that you probably spend most of your day at work and use most energy at night, batteries just makes sense. Naturally, you get different sizes, models, and quality options from world leading manufacturers.

  • Solar Charge Controller/MPPT

Just like the batteries, a solar charge controller is an optional component. It regulates the current used to charge the battery which comes from the inverter. However, a solar charger does become a necessity if you are using panels with high outputs. If you want to maintain the health of your battery and the overall efficiency of the solar array.

  • Solar Panel Accessories

Customize your solar panel system and gain a lot more control on your solar system. From monitoring, wiring, strut and other mounting components you can find everything you need to be able to fully commission your system. We have them all.

Converting the Solar Energy

Now, the silicone cell is the magical component that turns the UV rays into DC energy. Once the rays have been harvested and transformed into practical energy, in a manner of speaking, it gets sent to an inverter. The inverter takes the flow of energy through another transformation, switching it from DC energy to AC. The latter is the energy/electricity that gets used inside your home. And just to clarify, the inverter and the solar panel are two separate pieces of solar power equipment.

The Costs of Installation of a Solar System

Even though solar panels were expensive several years ago, in the past years the price drop has been dramatic. Now, it just makes more economical sense to invest in solar panels, because they give you some or full independence from the grid (depending on the size you install), save you money in the long run, and they are environmentally friendly.

In terms of actual pricing, everything depends on your needs and your budget. You can start by adding a solar geyser and test the efficiency for yourself. And from there you can install more.

The good news is that ZEROhomebills.com offers the most affordable panel from the best manufacturers with the highest efficiency levels, right to your doorstep. Only choose between our quality range of panels, which are just as durable as they are impressive.

Different Solar Panel Brands

Solar panels aren’t all made equal, which makes the brand of solar panel you choose very important. Essentially, the best way to know if brand is worth your attention or money is by getting to know them a little better. At ZEROhomebills.com by Solaranna, we only stock high-quality brands that prioritizes affordability. In other words, we want to make the best brands available to you at the best prices.

What Are the Benefits of Solar Panels?

Solar panels in the UK are an increasingly popular renewable energy technology. Based on national statistics by the Department for Business, Energy & Industrial Strategy, in 2017 the UK generated 3.40% of its total electricity using solar power. Source: Wikipedia. “ENERGY TRENDS – Table 6.1. Renewable electricity capacity and generation”(PDF). Department of Energy & Climate Change. March 2018. p. 71.

Besides being environmentally friendly, solar cells provide significant savings on your electricity bill. And whilst there are a few disadvantages, the long-term benefits of investing in solar panels far outweigh the cons.

If you are looking for a solar energy solution for heating, solar thermal is an affordable solution. Another option is installing thermodynamic panels (we are not selling them!) which are more expensive but can supply 90% or more of the domestic hot water needs.

Below is a list of the main advantages and disadvantages of this renewable source of energy:

ADVANTAGES OF SOLAR PANELS

Cuts Electricity Bills

Energy bills have in the past years increased by at least 7% per annum. You can protect yourself from the rising utility bills by incorporating solar panels into your energy mix. This will reduce your electricity bills significantly. So whilst utility costs continue to peak each year, having solar panels can help to reduce the impact. Also, keep in mind that the electricity generated from the solar panels is free.

Earn Money Back

Through Feed-in Tariffs (FiT) you can get paybacks for the electricity you produce. The Feed-In Tariff is an initiative by the UK Government aimed at helping you to become more self-sufficient and sustainable in your use of energy, whilst earning some extra income. The added value of the FiT is that payments are tax-free, index-linked, and have a 20-year guarantee.

Sell Back Electricity

If your system produces more energy than you need, through the generous tariff schemes, you can sell the surplus back to the grid. Thus, apart from cutting down utility bills, your investment in solar panels gives you a warranty for a state-backed income for the next 20 years.

Cuts your Carbon Footprint

Switching to solar energy cuts your carbon footprint, as it is a green, renewable source of energy. Unlike traditional electricity generators, solar power does not release any harmful carbon dioxide (CO2) or other pollutants. Estimates also show that solar panels for homes could save around one tonne of CO2 per year, which comes to approximately 25 tonnes over its lifetime.

All-Year Round Efficiency

Solar panels work all year round. Their full potential is released during the sunny months, but they also produce a considerable amount of electricity during the winter, as well as on cloudy days.

No Maintenance Required

Solar panels need almost no maintenance. Once the panels are installed, you need to keep them clean and check whether any trees begin to overshadow the solar PV array. Keeping the installation clean can be even easier when solar panels are installed on the roof are tilted, since rainfall can help clean dust off of the system.

With ground solar panels, maintenance may be more problematic, as the installation can accumulate dust, debris, snow, or bird droppings. Any dirt can be removed from the solar panels with the use of hot water, a brush, and possibly some washing-up liquid.

Independent of Grid

Solar panels are ideal in remote areas where extending power lines to connect with electrical power grid would be too expensive. They are an affordable and effective solution for isolated homes in the rural areas of the country.

There is also the possibility of integrating batteries in solar cell systems, and this can be used as an energy storage. Batteries store energy gathered by solar cells, saving it for rainy days or for use throughout the night. Solar battery storage system costs are not low, ranging typically between £1,200 and £6,000 depending on the size and capacity. However, technological developments are leading to new solutions and will eventually come up with a great solution for solar energy at night.

DISADVANTAGES OF SOLAR PANELS

High Initial Cost

It comes as no surprise that solar panel costs are initially high. Although, a number of subsidy programs, as well as government rebates, help to counterbalance the expense. As new technologies in the solar panel field emerge, prices for solar panels are expected to continue to decrease making the investment more affordable.

Dependence on Sunlight

Solar panels are dependent on sunlight, and while this does not necessarily mean direct sunlight, they are most efficient in locations with bright and direct the sunlight. Thus, they cannot produce energy during the night and are less effective during dark winters. The effective solution for this is, therefore, to switch to the main power grid at night. Alternatively, homes with a standalone system can store energy in batteries during the day to be used at night.

Solar Panel Placement

An inaccurate placement of solar modules can be a major hindrance on the effectiveness of electricity generation. The ones who are most affected by this are homes that are covered by trees and landscapes. In the same way, if you live in an area surrounded by large buildings, the effectiveness of the panels will be limited. However, the effectiveness can be increased by adding more panels to your rooftop to generate a sufficient supply of electricity.

How Much Do Solar Panels Cost?

It is difficult to calculate the exact cost of solar panels due to the many factors that can affect the price of solar panels. The average domestic solar array for electricity may cost between £2,500 to £9,000.

Generally, the more expensive the system, the more electricity it generates and therefore the more savings it can bring. In contrast, installing a typical solar heating system is much cheaper. Prices can vary from £1,500 to £5,000 depending on the size of the installation and its features.

It is important to note that despite solar panel costs being known to be expensive, in recent years the prices for solar panels have dropped considerably, and improvements in technology have led to more efficient systems, making the advantages even more tempting.

The Installation Process of the Solar Panels in 7 Steps

1st Step: Erecting the scaffolding

The first step in the process is to erect the scaffolding. This will ensure safety for the installation team when they are on the roof

2nd Step: Attaching Roof Anchors

After the scaffolding is set, the installation team arrives. The team starts out by attaching the roof anchors, which will hold the base for the solar panels. The types of anchors used depends on the type of roof tile fitted on the roof.

3rd Step: Attaching the Frame

The next step is to attach the frame, which is made up of aluminium bars. The bars must be fitted in a straight direction and parallel to one another.

4th Step: Installing the Solar Panels

Once the frame has been attached, the installation of the solar panels themselves can begin. The panels are clamped to the aluminium frame, but initially not too tight so as to permit adjusting on the frame. Once they are set up at the desired position, these will be firmly anchored.

5th Step: Wiring the Solar Panels

Now that the panels are fastened securely on the frame, the next step is to wire them. In most of the cases the panels come wired from the manufacturer, however, these need to be connected to the inverter, which would typically be in the attic of the household. The inverter is a component of the panel system which converts absorbed energy from the panels into DC electricity, which can be used by the household appliances. Be prepared to replace your solar PV inverter every 5-10 years, as these machines tend to have shorter lifespans than solar panels.

6th Step: Final Connections to the Consumer Unit

After the panels are wired to the solar inverter, the final connections to the consumer unit will be made. A generation meter will also be connected, whose purpose is to monitor how much electricity the solar panels actually produce. During the time of the wiring installation, the electricity supply to the household will need to be shut off.

7th Step: Testing the panels

After the wiring is set up to the inverter, together with the generation meter, the installation is nearly finished. Now the only thing left is to switch the power on and test the system. Once this is complete, the installation is officially over and the system can start working.

Planning Permission for Solar Panels

In EnglandScotland and Wales you are not required to apply for planning permission for most of the domestic solar panel installations (both heating and electricity). It is important to note, however, that the installation must be below a certain size. If your solar panels protrude more than 200 mm, you will need to apply for permission first. There are also other local restrictions that might affect whether you need permission or not; especially in Scotland. For example, when the building is within a conservation area of World Heritage Site. Therefore, it is advised to ask your solar installer to check, whether your installation meets all the requirements.

Planning Permission for Solar Panels limitations

Solar Panels and Insurance

In most cases, when you install panels on your roof, your insurance should cover you under the current terms. However, since the solar panel installation means a change to the home structure, it is advised to always contact your current insurance provider before taking on the installation. It is important to note that your home insurance may not include a cover for damage or theft to your solar panels. To avoid any uncertainties, it is advisable that you consult your insurance policy to confirm that your panels are covered.

Installing solar panels are a worthwhile investment for both homes and companies. They ensure greater sustainability, reduce utility bills and in the long run help you to put money back into your pocket.
