I was skeptical but very hopeful when I attended a discussion on Sierra Club’s campaign called “Ready for 100“. The goal is to get to 100% renewable energy for ourselves, our towns and our country by 2050. I’m very hopeful because we have to get there to prevent very serious and irreversible damage to the planet, and I want to believe it can happen. At the same time I was very skeptical because I don’t think we have the political will especially at the local, state, and federal government.
As a REALTOR® , I am asked if solar systems increase the value of a home for sale. My short answer is “yes” – solar PV definitely adds a premium to a home’s value; however, quantifying that additional value depends to some extent on the appraisal process.
Ben Hoen, a researcher with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, and Sandra Adomatis, an appraiser and specialist in appraisal of solar systems, authored “Appraising into the Sun: Six-State Solar Home Paired-Sales Analysis”. This report was based on a 2015 study of samples taken from a database of 4000 home sale transactions in California, Florida, Maryland, North Carolina, Oregon and Pennsylvania, combined with an evaluation of 43 pairs of home sales in local markets within each of these states, thus combining the paired sales method typically used by appraisers, in which the sale of a home with solar PV is compared with the sale of a comparable home without PV, with a statistical analysis of the larger database . The report concluded that the average premium for a home with PV in this study varied from 2.5% to 6.4% of the sale price, depending on the location.
Almost two decades ago the Energy Star rating system was introduced to help consumers understand something about the energy requirements of one product compared to another. The idea is that even a little bit of information posted on an appliance can get people thinking about saving energy and saving money.
The future of interconnection of solar arrays to the utility grid in NH, net metering, is being taken up by the State Legislature this session. As the Utilities have met their minimum (“solar cap”) and are not required to allow interconnection of solar arrays to the grid, the natural question of what is next for solar automatically arises.
First it is important to understand why we need the grid. The power grid provides electricity to many customers across a large region. The grid has the ability to
