Lawmakers gave final passage to bills to study geothermal heat pump systems, promote electric vehicle charger installation and require status updates of residential solar systems in home sales.

State regulators cut incentives for residential solar and increased them for some non-residential projects after a report said the latter missed targets.

The New Jersey BPU granted waivers of rules governing its solar incentive program, a sign of the agency’s strategy as the state struggles to reach its  goals.

Solar advocates question whether developers will be willing to go through a complicated application process without knowing the value of incentives.
