How does Solar work?
Solar panels when exposed to sunlight generate DC electricity. This DC electricity is fed into your Inverter, which converts it to AC electricity, the type that is used inside your home. When the sun is shining during the day, your household power will first come from what your solar system is producing, and only buy the extra power it needs from the grid. If you’re not at home during the day and therefore not using much power, the extra power your solar system has to spare will be fed into the electricity grid, and your power company will pay you for this excess energy by way of a reduction on your power bill. At the end of the day when there is no longer enough light to power your Inverter, your system goes into a standby mode and will restart again in the morning when the sun comes up.
How many panels do I need?
It depends on your level of energy consumption. A quick assessment of your latest energy bill can give us a better idea of your requirements. As a simple rule of thumb, check your total consumption for your billing period (this will be in kWh), and divide this by how many days your bill was for. This will give you a daily average in kWh. That number will roughly equate to how many solar panels you should have installed, assuming of course you have sufficient roof space to install them. Any size solar generation system will reduce your power bill, and of course the larger the system the larger the energy savings.
Is my building suitable for installing solar?
Several things need to be assessed to check if your home or business is a good place to install solar. Things like shade that could be cast on panels from nearby trees or buildings need to be taken into account, as well as the orientation of your roof, and other factors that could reduce your systems overall energy output. Any potential reduction in output will be discussed frankly on site with you.
How long will my Solar system last?
Good quality solar panels will generally last 20 years with little reduction in output. Inverters generally last 10-15 years due to having electronic parts inside. Most decent quality panels have a warranty of 20-25 years, whilst the reliable inverter brands will provide 5-10 year warranties.
