Residential solar buying trends: Quality matters, storage interest increases

residential solar buying

At Bloomberg’s Future of Energy Summit in New York, EnergySage released its latest semiannual Solar Marketplace Intel Report. EnergySage’s report is based on millions of transaction-level data points generated within its Solar Marketplace, and serves as one of the country’s foremost leading indicators of the future of residential solar shopping.

This sixth and latest report features new datasets and analyses including complete visibility into the specific brands of solar panels most likely to drive sales on EnergySage, and what other energy-related products and services today’s solar shoppers are considering, such as the Tesla Powerwall home battery.

Here are three insights from the latest report.

Equipment quality, not lowest price, drives buying decisions

EnergySage reviewed the equipment that consumers chose most frequently on the Solar Marketplace. In 2017, the most successful quotes all included higher quality panels such as SunPower, LG and Panasonic. This reflects a broader trend seen throughout the report: prospective solar customers are compelled by offers that include quality products at the right price.

Three in four solar shoppers also considering energy storage

In 2017, 74% of solar shoppers who shared their non-solar energy interests with EnergySage stated they were also considering a home battery like the Tesla Powerwall. While this hasn’t yet translated into an equivalent sales volume, batteries present a massive new market opportunity for installers, manufacturers, lenders, and utilities to capitalize on in coming years.

Cost of solar continues to fall, the lowest prices seen to date

When EnergySage first started tracking the cost of solar offered to consumers in 2014, the national average was at $3.86 per watt. By the end of 2017, the national average had fallen to $3.13 per watt. In many parts of the country including Florida, Arizona and Maryland, average costs were below $3.00 per watt on EnergySage and as low as $2.00 per watt in some counties.

“Today’s residential solar consumers are opting to own their systems, and as our data shows, they’re prioritizing equipment quality and value over whatever is the cheapest option,” said EnergySage CEO and founder Vikram Aggarwal. “Our mission to make solar more accessible and affordable for Americans through transparency is allowing today’s solar shopper to find the right solutions at the right price.”

Additionally, EnergySage analyzed quotes submitted to Solar Marketplace shoppers in five different utility service territories. The report compared the cost of solar energy to today’s electricity rates in territories served by Green Mountain Power, Pacific Power, Puget Sound Energy, San Diego Gas & Electric, and Tampa Electric. Remarkably, in every utility service territory except for Puget Sound Energy, the cost of solar was at least 50% below the 2017 residential electricity rate offered by the utility, and often lower.

California retirement community expected to save $250,000 a year with Sharp solar+storage system

Sharp-SmartStorage-Hi-Res

The NW Photon Energy and Paradise Village Retirement Community, a senior Independent Assisted and Memory Care Community in San Diego, Calif., is adding a 240 kW/324 kWh SmartStorage system from Sharp in six buildings on the community’s grounds and integrated with 516 kW of solar PV. The decision was a no-brainer after a detailed analysis of Paradise Village’s energy usage revealed that the hybrid solar plus SmartStorage system is expected to yield an estimated $90,000 in demand savings annually. Additionally, when factoring in the solar PV system coupled with the SmartStorage system, Paradise Village can expect to save over $250,000 a year on its utility bills (this includes both energy and demand savings).

“The significant savings unlocked by addressing peak demand may have a positive impact on the quality of life for the seniors in Paradise Village’s care, so we’re very proud to be involved in this project,” said Carl Mansfield, General Manager and Founder of Sharp’s U.S. based Energy Systems and Services Group. “In addition to this retirement home, we’ve now had SmartStorage systems installed at a wide variety of facilities such as lumber yards, non-profits, service stations, school campuses, manufacturing plants, and more. This demonstrates how economically impactful our energy storage system can be for virtually any commercial and industrial building that is struggling with high utility bills that are punctuated by expensive demand charges.”

Paradise Village is a resort-style Independent, Assisted Living and Memory Care Community located in San Diego Gas & Electric’s (SDG&E) utility territory. The multi-building community consumes a significant amount of energy from HVAC, refrigeration and a variety of medical equipment that can have a significant startup load, which in turn increases demand request peaks with SDG&E. In some parts of California, up to 50 percent of commercial utility customers’ bills are a result of demand charges, making them ideal candidates for solar plus SmartStorage systems. It is estimated that Paradise Village’s system will reduce demand by over 2,000 kW annually.

Paradise Village’s SmartStorage system installation is backed by Sharp’s innovative 10-year Asset Management Service Agreement, which provides routine and unscheduled maintenance coupled with a 10-year demand reduction performance guarantee. If guaranteed demand reductions are not met within the terms of the agreement, Sharp will compensate for the deficit in promised peak demand reductions.

LG Electronics joined Cypress Creek Renewables, the nation’s fastest-growing solar farm developer, to celebrate the official opening of one of largest solar-plus-storage installations in the continental United States – an 8.5 megawatt portfolio of utility-scale solar projects, with storage capacity of 12 megawatt hours, in North Carolina.

All told, 21,900 high-performance LG solar panels (395-watt LG NeON 2 72-cell modules) have been installed across a dozen separate solar farms in Columbus and Brunswick counties. LG Electronics provided tax equity financing to the projects in partnership with Cypress Creek.

Cypress Creek acquired the projects from United Renewable Energy, the initial developer of the projects. The power developed on these sites will give the local homes and businesses in the area access to clean and affordable energy. The LG solar panels will charge batteries during off-peak periods. Once the batteries are charged each day, the solar portion of the projects will continue to deliver energy to the grid. During peak load times in the summer and winter, the projects will provide reliable renewable energy using the batteries, and LG solar panels will reduce the utility’s peak power requirements.
