While solar panels generate electricity in direct current, or DC, the electric grid and homes generally use alternating current, or AC. In cases where shading is unavoidable, solar panel installers often mount panels fitted with bypass diodes or microinverters to mitigate the effects of shading. They emit gas when charged so its strongly advisable to install them outdoors or in an area with good ventilation. According to the NREL data above, installation typically accounts for 5.5% of the total cost of a residential solar project, so this equation will get you a ballpark figure for labor costs.
