General Solar Power FAQs
What is PV?
PV is short for photovoltaics (photo=light, voltaics=electricity). PV is a semiconductor-based technology used to convert light energy into direct current (DC) electricity, using no moving parts, consuming no conventional fuels, and creating no pollution.
How long will a Solar PV system last?
All panels installed under the scheme by approved agents will continue to generate efficiently for at least 25 years. Over this time their output will diminish slightly but they should still perform at 85% at the 25 year mark according to the scheme rules. Manufacturers have invested heavily to ensure their products meet and in most cases exceed these targets.
I use 95% of my electricity after 6pm - should I get solar?
You’ll always get the best return from solar if you self consume a decent (over 30%) amount of your generated solar energy.
How does electricity get stored for use after sun goes down?
Generally, grid connect systems direct excess electricity produced during the day back into the local electricity grid; so there is no on-site storage as such. You then receive credit for any power that you put back into the grid. At night time, you automatically use electricity straight from the grid. Off-grid systems store energy produced during the day in deep cycle batteries for use as required.
How do I know what size system is best for me?
How is Solar operated at night?
During Daytime Solar energy is stored in battery-bank, which in turn is used at night.
