Mr & Mrs B. contacted us as they wished to install Solar PV on their house. The usable roof area was only 20sqm. Other installers they had spoken to needed over 25sqm for 16 panels to provide a 4kWp system whereas Stratford Energy Solutions, using the world’s highest efficiency panels from SunPower, could do it with 12 using the E20 333W panel.
The black panels provide market leading generation of 204w/sqm, have the lowest degradation of only 0.2% per year and come with the world’s only combined 25 year product and performance guarantee.
