With energy secretary Amber Rudd promising to deliver a solar revolution during her tenure, NAPIT has urged installers to get involved with the technology.
Over the past year, solar PV installations have been increasing in the UK, making it the largest growth market for the technology in Europe.
Generation doubled in 2014 compared with the previous year.
NAPIT Certification managing director David Cowburn said: “To maintain the recent growth of solar PV, NAPIT are pushing for continued stable Government support through the Feed in Tariff (FiT).
“This would enable the domestic market for solar PV to continue on the trajectory to cost-neutral and no longer need Government support, providing a stable future for solar PV installers.
“To ensure this happens the Government must leave the FiT scheme untouched; allowing the continuation of stable growth whilst managing costs through effective degression. Through recently published campaign infographics, NAPIT have effectively summarised the FiT policy and set out potential risks and proposals to mitigate these.”
