Installing a Solar PV system is a great investment that will reduce your electricity bills, reduce your carbon emissions, protect you from rising energy costs and generate an additional income through the Feed-in Tariff scheme.
RenEnergy have installed over 400 domestic PV systems but no two are alike. Our Technical Sales Consultants will discuss your requirements in detail and recommend the best products for your needs.
During the installation phase you will be looked after by one of our experienced Project Managers who will act as your point of contact and will ensure that the installation runs smoothly with limited disruption.
- How Does PV Work?
A solar cell is made of a semi-conductor – silicon. A thin wafer of silicon is treated to form an electric field, which is positive on one side and negative on the other; electrical conductors are attached to the positive and negative sides.
When light strikes the solar cell, electrons are knocked loose from the atoms, the electrons are captured in the form of an electrical current flowing through the conductors from positive to negative and this is what makes electricity.
A group of solar cells electrically connected to each other and mounted in a frame is a solar panel. A group of panels is called an array. This is created in DC power, which the inverter changes the power from DC to AC power that can be used.
- What are the benefits?
Cut your electricity bills. Sunlight is free, so once you’ve paid for the initial installation, your electricity costs will be reduced.
Get paid for the electricity you generate. The UK government’s Feed-in Tariff scheme pays you for the electricity you generate, even if you use it.
Sell electricity back to the grid. If your system is producing more electricity than you need, you can sell the surplus back to the grid through the Feed-in Tariff scheme.
Cut your carbon footprint. Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year – that’s more than 30 tonnes over its lifetime. Solar PV provides a stable long-term low maintenance.
- Will I need three phase electricity?
In general systems over 10kW will require three phase connections.
- Will I need planning permission?
All ground-mounted systems require planning. In most areas roof mounted systems fall under permitted development but you will still need to check with your local authority.
- How long will an installation take?
It depends on levels of demand, the size of the installation and whether G59 approval is required. It can be anywhere between 1 – 3 months. Planning regulations have been relaxed for Solar PV systems however if planning is required it can take up to 8 weeks. The actual on Site work will take approx. 5 days for 50kW installation and 1 day for a domestic.
- Is my property suitable for PV?
A common misconception is that only perfectly south facing roofs will deliver efficient and lucrative solar PV generation. When in reality, anything from due east to due west can be considered for an effective roof-mounted installation. Ideally we would look for a roof pitch between 0-45° in order to maximise benefits, but with clever design we can overcome most challenges. To maximise the benefits of an array, a roof-mounted system will need to match these criteria fairly closely. If you don’t have a suitable roof we can explore ground-mounted options.
- What happens if I move house?
The PV array will increase the value of the property asset. You can also retain ownership of the roof and receive the FiT payments for the lifetime of the tariff.
