How To Install Solar Panels And Batteries

Have you decide to purchase a solar system for your home and wondering how to go about the installation? If yes, then we’ve got you covered! In recent times, it’ll be totally safe to say that solar panels and batteries for home use in the UK has now become more of a necessity than a luxury considering the numerous benefits the system offers. However, with the cost of having the system installed, you might be forced to think about the doing the installation yourself.

If you lack proper training and experience in the solar system installation process, it’s advisable to hire the services of a qualified technician who can guarantee the best results the first time and help you save time and extra costs that may result from possible costly errors. Here, we’ll give you a good insight into the installation process.

• Mount the solar panel and ensure it’s properly screwed to your roof. Try to position in such a way that it faces direct sun rays to have enough solar power generated.

• Connect your charge controller. The current that’s being generated by the solar panels will not be stable all day long. As a result, it’s important to avoid connecting solar photo voltaic modules directly to your better, if you don’t want it damaged. To control the current received from the solar panels, the charge controller is required. It has three connecting points - one for the battery, one for the solar panels and the last for Direct Current (DC) identify the one for solar panels and connect accordingly.

• Connect the battery to charge controller. The charge controller possess two terminals for the battery - the positive and negative terminals. Connect the positive terminal to the positive of the battery and also do the same for the negative.

It’s important to get the right size solar panel system for your commercial property. Solar panels are usually installed on pitched roofs, although they can be fitted on stands on the ground if you have some unused outdoor space. The more panels you install, the more power you’ll generate, but there’s no point buying more panels than you have space for.

Solar panel system sizes are measured in kW. 4-10kW solar panel systems are usually too big for domestic properties but are ideal for smaller commercial properties. Here’s an idea of how many panels and space you’ll need for a few different system sizes:

System size, Number of panels, Area required (approximate)

4kW, 16, 23m²

6kW, 24, 35m²

8kW, 32, 46m²

10kw, 40, 58m²

Bear in mind that solar panels can’t be less than 30cm away from a roof edge, so you’ll need more space than the area that the panels take up.

Solar energy comes from the sun. Solar panels absorb sunlight, and convert it into electricity. This can be used to power heating systems, lighting and appliances. You can also get solar thermal systems, which use solar energy to warm hot water.

Solar energy is a type of renewable energy, because sunlight is considered to be in unlimited supply.

Solar PV panels work by converting sunlight into electricity. They’re made up of photovoltaic cells, which take in the sun’s rays and turn it into direct current (DC) electricity. The current is then channelled into an inverter, which converts it to alternating current (AC).

Once converted to AC, the electricity is ready to use. It’s fed through a meter and into your property’s consumer unit, and is automatically used to power appliances and heating systems. Your system will automatically switch between your solar electricity supply and the national grid, and export any solar electricity you don’t use to the national grid.

If you want to test your solar panel system to see if it’s working properly or just to see what output it’s giving, you can do this using a multimeter to measure current, or amps, and voltage.

Before you start, you’ll need to find the voltage (v) and current (A) ratings of your panel. You should be able to find them on the back of the panel. You should also make sure that it’s a nice clear, sunny day to get the best readings out of your panel. You should also check that it’s safe to be up on your roof!

To measure open circuit voltage, you’ll need to make sure that your solar panel is completely disconnected from your system’s regulator and battery (if you have one). Angle the panel towards the sun, and ensure that your multimeter is set to measure volts. Measure the voltage between the positive and negative terminals by connecting the negative contact on the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel.

Then, you can move on to the short circuit current. Follow the same steps as the open circuit voltage, but ensure that your multimeter is set at 10A to start with.

Only try to test your solar panel if it’s safe to do so. If your roof isn’t accessible without scaffolding or specialist equipment, consider speaking to an MCS-registered solar company about your concerns. They may recommend that they come to service your solar panel system.

When you’re about to transform from the standard electricity to solar energy, what determines your solar system’s size is the amount of solar that’s required. The amount of solar that you’ll need, on the other hand, requires considering the end goal, be it to increase money savings, reduce environmental contamination, maximize Returns On Investment ( ROI), or just to copy what the neighbour’s done.

In order the determine the number of solar panels that is needed, the first step would be to calculate the number of kWhs that’s currently being used. A kWh is what’s used to determine the amount of energy that has been incorporated over time which the utility uses to bill you. What’s strongly recommended to create a suitable range is a 6 to 12 months average of your household electricity bill. Other factors that can play a key role in the determination of the number of solar panel needed include the following:

✓ Sunlight exposure hours. In order to know just how much energy your solar panels will generate, there’s a need to know the number of direct sunlight hours you should expect on a daily basis. For example if you stay in a region that’s usually very sunny, then it’ll be reasonable to expect more energy production per panel than regions that are usually cloudy.

✓ Angle and size of the roof. Roofs with a lot of workable space may require to let go of some efficiency opting for larger and cost effective panels to achieve the targeted energy. However not all homeowners have sufficient roof space or shade coverage for the solar panel they actually want. Also, the degree at which the roof slants will also determine if the sunlight is hitting the panels well enough and the amount of energy that can be generated thereof.

It may be hard to believe with the summers we have in the UK, but there is more than enough sunlight to power solar panels. Solar PV (photovoltaic) panels operate in daylight, rather than needing direct rays from the sun so they’ll work throughout the year.

One of the things that has been on the UK government’s agenda for some time now is to promote the use of renewable energy sources. In fact, the Renewable Energy Directive put out by the EU instructs all member countries to achieve a 20 percent renewable target before the year 2020. The UK’s commitment to this objective has been made quite glaring with a number of funding options that has been put in place to help business owners looking to solar panels on their properties. This commitment was also showcased by a reduction in the cost of solar panels, so new investors have little to worry about. Although there aren’t any grants in the conventional sense, but there are opportunities for solar panel funding in the UK. At present, the only scheme open to new applications is the SEG - Smart Export Guarantee which came into effect on 1st January, 2020.

In general, there are four notable incentives in the UK for solar panels which includes the aforementioned Smart Export Guarantee, Reduced VAT on Energy Saving Products, Feed-in Tariff ( no longer open to new applications ), as well as the Renewable Heat Incentive ( RHI - applies only to solar water heating ).

Being the only one still open to new applications, we’ll provide you with some insights on SEG. The Smart Export Guarantee allows small scale low-carbon electricity generators to receive payments for surplus energy they’re able to export back to the grid. Although, this is not a direct government scheme, all licensed suppliers are necessitated to offer an export tariff to their customers. Those suppliers with more than 150,000 customers are obligated to offer a tariff, while the suppliers with fewer customers can partake on a voluntary basis.
