Risks to getting solar power (according to Project Sunroof) are something to consider.
> As with any investment, there are some risks, though a well-installed system will make most risks extremely rare. Risks include PV systems catching fire, installations leading to roof leaks, theft, obsolescence, and hail damage and/or wind damage to the solar system itself.
> Fast-growing trees can shade solar installations, reducing production over time. Utilities can change how much they charge their customers for electricity, changing the savings from solar.
