Costs and Maintenance

There is no flat rate for a solar PV system.

Capital costs vary according to the scale of system and this is determined by your electricity demand and the nature of your site. As PV is a versatile technology, systems can be made to almost any size, with prices to match accordingly.

Another variable influencing cost is the type of PV module you chose. Costs can vary considerably between a standard above roof crystalline module, integrated PV roof tiles or a be-spoke glass facade.

In addition to PV type, there is also the cost of accompanying system components and peripherals – that is, the 'balance of system' (BoS) cost. The BoS includes inverter, electronic display(s), mounting system, switches, cables, charge regulators, meters and connection to the grid (or batteries and charge regulators for off-grid systems).

There is also the cost of installation work.

As a rough guide, smaller systems typical to multiple housing schemes cost in the region of £6,500 (inclusive of installation); costs for larger systems, such as those installed for schools, commonly start from around £15,000. As with other types of renewable energy systems, savings can be made if construction or engineering work is already underway at your site.

A particular advantage of solar PV, even over other types of renewable energy system, is that running costs are very low – it requires no fossil fuel to run and, since there are no moving parts (unless a tracking device is used), very little maintenance.
