Solar Products - Price Guide
Perpetual Energy designs, supplies, installs and maintains PV systems that generate renewable electricity from solar energy. We have a range of solutions to suit most roof types e.g. membrane based systems for flat roofs. Below is a list of budgetary prices to install an array of PV modules for your project.
Contact us for details on how we can help progress your PV project.

*All guide properties are assumed to have sufficient roof structure to support the added weight of PV development. Outputs are estimated assuming that roofs are free of localised shading, sloping roofs are facing between south west and south east & the value for average solar irradiance is a constant value throughout the UK. Estimated installed costs are guide prices and do not constitute a firm offer.
*Installed cost includes:
-
Mechanical hardware – mounting structure for panels
-
Electrical hardware – modules, inverters & grid connections
-
Labour – installation and commissioningStandard concrete pad foundation in accordance with manufacturers design
*Excludes:
-
Site modifications & delivery ex works – access, structural surveys etc
-
Permitting costs (planning, etc)
-
Additional design costs, cabling & electrical connections
-
Communication costs if applicable

Transitional arrangements:
Pre 15 July 2009 - all sub50kW units registered under RO will be transferred to FIT (9p/kWH).
All sub50kW units not registering under the RO as of 15 July 2009 will NOT be eligible for FITs.
Post 15 July 2009 but pre FIT implementation date - all units will be eligible for FIT tariff as if they were installed post FIT implementation. No retrospective reward for the interim period will be delivered over and above the 2ROCs currently available.
LCBP grants and other grant will NOT effect FIT eligibility.
