Technical FAQs 4

Is there a guide to rooftop solar & Bess?

To help homeowners tackle this tangle of information, PNNL researchers Jessica Kerby and Bethel Tarekegne published an open-access guide to rooftop solar and BESS in Renewable Energy Focus.

What are the electrical safety standards for rooftop PV & Bess installations?

Standard Guideline-Enhancing Electrical Safety Standards for Rooftop PV and BESS Installations in ASEAN through Safety Features Application Chapter 2 11 are not normally live, but have become energised due to a fault, typically an insulation failure. Indirect contact is particularly insidious as it can occur during normal equipment use.

How long should a solar roof last?

A minimum design life of 20 years. Planning, and local authority requirements. The age, condition, and construction of the roof (for roof-mounted systems). considering the current age, the design life of the roof, and the requirement of the solar PV system to have a design life of 20 years.

How much would a rooftop solar system cost without Bess?

Without BESS, the same household could install 10 kW of rooftop solar, which would cost $28,700 and save $1,567 per year. PGE and the state of Oregon both offer incentives for rooftop solar and battery energy storage. With the utility, state, and federal incentives, the combined solar and BESS system could be paid back within 11 years.
