Solar Photovoltaic
Solar Photovoltaic systems (Solar PV) use sunlight to generate electricity. Although direct sunlight allows Solar PV systems to work at full capacity, they only need daylight to produce electricity.
With no moving parts and having been designed to withstand the elements, the PV modules are guaranteed for at least 20-25 years. The life expectancy of our PV modules far exceeds this. PV Systems generate no greenhouse gases, saving approximately 325kg of carbon dioxide per year.
Basic Requirements
- You can install solar PV panels on a building with a roof or wall that faces within 90 degrees of south, as long as no other buildings or large trees overshadow it.
- You need a minimum roof area of approximately 10 square meters.
- Solar panels are not light and the roof must be strong enough to take their weight, especially if the panel is placed on top of existing tiles.
- A grid connection is needed; this also allows your supplier to buy back any excess power generated by your PV cells.
PV arrays come in a variety of shapes and colours, ranging from panels to transparent cells that you can use on conservatories and glass to provide shading. Another alternative are 'solar tiles' that look like roof tiles which as well as enabling you to generate free electricity they provide an interesting alternative to conventional roof tiles.
Costs and Benefits
- Cost approx £6,000 - £20,000 for a domestic system, which will produce around 50% of your electricity needs. Grants are available.*
- Installation takes between 3 - 5 days.
- It is extremely low maintenance with a lifetime of 30 years or more.
- Generates clean, inflation proof electricity.
- Could increase the value of the property.
- Silent and unobtrusive.
