How long your solar panels will last depends on their age and quality. Most modern solar panels have 20-30 year warranties, but this doesn’t mean that they’ll stop working at this point. Many will stay at a good efficiency level for up to 40 years, while others will start to decline earlier.

small Commercial solar panel system FAQs
Solar energy is renewable, as the sunlight it uses won’t run out. This means that it’s a great way to generate electricity without damaging the planet. So, installing solar panels to generate solar energy can be a great move for businesses looking to reduce their carbon emissions.
Solar panels can be pretty expensive, so require an initial investment. However, a quality solar panel installation can be very financially beneficial, saving you money in the long run. It does this in two main ways.
Firstly, using electricity generated by your solar panels means that you have to use less power from the national grid. Once you’ve bought your solar panels, your solar electricity is essentially free, meaning that you’re saving money by using this instead of power supplied by your energy company. If you want to maximise these savings, invest in a solar battery so you can store unused solar electricity ready for when you need it.
You can also earn money with your commercial solar panels through the Smart Export Guarantee [https://solar-panels.quotatis.co.uk/smart-export-guarantee/]. This is a government scheme that says that all licenced energy suppliers with 150,000 customers or more have to offer a tariff to renewable energy generators. When you generate solar electricity but don’t use it immediately it gets fed back to the grid – the tariff pays you for every kWh of this.
At the moment there’s no minimum tariff that an energy company has to offer – it only has to be above zero. However, many energy companies are competing to offer the best deal, so you can definitely find a tariff that will pay you for all the unused solar electricity you generate.
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.
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.
