House Valuation

• PV adds $20 value for every dollar of energy bills saved - so if you save $1000/year the house is valued $20k more [1]. A 6kW system costs $18k in 2023 [2]. This means it is just about even to add solar to a home prior to selling - based on economics of PV install and added value captured. However, the benefit to the buyer is greater - PV lasts 20 years - but that is only to the 90% point - the PV will actually live much longer, with 70% of the original efficiency after 40 years! [3]
• 2 car garage - $23k value added to a house - [4]. This one says $50k [5]
