What features should my PV system have?

Some PV systems use batteries to provide back-up power to your home or business in case of utility grid outages. While batteries certainly add value to your system, they also add cost and maintenance. Keep in mind that batteries and other electricity storage devices are not covered under most incentives. You should also consider the “economies of scale” associated with your system, which means that a larger system costs less per KWh generated, even though it costs more overall. You are likely to receive a better price to install a two KW system all at once rather than one KW this year and one kW next year because multiple orders and multiple site visits are more expensive. On the other hand, putting a system together in this “modular” fashion may be more attractive financially, as it allows a pay-as-you-go approach.
