Welcome to the Solar Subreddit

Before submitting posts in this subreddit, read the current subreddit rules, suggestions, and helpful links post which is stickied to the top of the post list

This subreddit is for solar photovoltaic (PV) professionals, owners, and enthusiasts. The solar module and the systems it drives - whether small residential installations or large, utility-scale power plants - is one of the great inventions of the modern age. Steady improvements in materials, design and labor have dramatically lowered costs, module efficiencies have improved gradually as well - both serving to make the technology much more competitive against fossil fuels in recent years. What changes when solar PV is combined with batteries? What is the global impact of solar PV on the overall energy industry? When will solar become affordable for all? Shine on you brilliant solar enthusiasts!

Be sure to check out our wiki for more solar information and resources.

Tip for help requests - because of variances in things like regulations, prices, and amounts of solar radiation, it is useful to provide general location info such as country and state when asking for help/info regarding your solar project.
