San Diego Gas & Electric Co. said that it has developed a money-saving alternative for residential customers who want to install solar panels.

The utility said its renewable meter adapter can connect rooftop solar systems to a house’s existing electric meter panel in as little as an hour. SDG&E said the hardware costs around $1,325, while conventional panel upgrades can cost more than $2,500 and can mar paint and stucco.

The adapter contains a meter collar with a 60 amp circuit breaker and a fused disconnect box that can accommodate up to an 11.5 kilowatt system.
