Solar battery warranties: what’s covered, and what’s not?

Tesla Powerwalls, Panasonic Evervolts, and sonnen eco – all of these batteries come with a 10 year warranty. However, simply comparing the length of one warranty term to the next doesn’t give you a full picture: what is and isn’t included in a warranty differs quite a bit from one battery company to the next. And considering how important a battery system is for resiliency and–in some markets–savings, you want to make sure you’re covered in case anything goes wrong.

In this article, we’ll review the most important aspects of a battery warranty, and discuss what’s standard for the industry.

Adding a battery to your solar energy system as a retrofit

The market for home energy storage options like the Tesla Powerwall has taken off in recent years, and costs are falling quickly. Many homeowners and businesses are thinking about adding a battery backup to their solar panel system.

The benefits of a home battery can be significant, especially if you have solar: you can use more solar energy onsite, or save it to use as backup power in the event that the grid goes down. If you are on time-of-use (TOU) rates for your electricity or pay monthly demand charges, you can even save money by using power from your battery when rates are high.

Going off-grid with solar: what does it mean and how much will it cost? (Part 2)

This is Part 2 of a two-part series that explores the economics of going completely off-grid with solar. Part 1 focuses on what it actually means to go “off-grid” and how to start thinking about calculating the costs for cutting the cord with your utility. Part 2 discusses two real-world examples of sizing an off-grid solar energy system, along with the feasibility of going through with an off-grid solution. Check out Part 1 here.

Top EnergySage articles of 2020

Let’s all breathe a big sigh of relief – 2020 is almost over! Despite some hurdles, solar energy had a strong year full of exciting news and milestones; in their 2020 World Energy Outlook report, the International Energy Agency (IEA) proclaimed that solar will be the “new king of electricity,” the world’s largest solar plant went live in October (2.2 gigawatts!), and just this week, the federal government extended the 26 percent solar tax credit for another two years.

To finish off the end of a long year, we’ve pulled together a list of our most popular articles of 2020, as chosen by you, our readers.

SGIP 2020 program updates: what you need to know

(Updated November 2020)

California’s Self Generation Incentive Program (SGIP) is one of the first incentives for battery energy storage in the country. The program has been very successful, helping California to lead the nation in residential energy storage deployment. Recently, the program has received additional funding, with a slightly revised charter for how to use those funds. Below, we detail the adjustments to SGIP and how it will impact individual, residential solar + storage shoppers in California.

Backup generators vs. energy storage: do the math

More and more homeowners are looking for ways to improve the resilience of their home’s electricity systems. Historically, many people who wanted backup power for their homes in the event of an emergency–think natural disasters and other outage events–looked to back up generators for that resilience. These days, however, homeowners are increasingly looking to energy storage systems, and solar plus storage systems in particular, for that peace of mind during outages.

Why utilities want you to have a battery

Although utilities and the solar industry haven’t always had the most positive relationship across the country, there’s one distributed technology that utilities have been very quick to embrace: energy storage. When installed at a home or business, energy storage systems provide myriad benefits to both the owner of the system, as well as to the electricity grid as a whole. As a result, many utilities throughout the country are now actively encouraging the adoption of energy storage systems. Here are just a few of the reasons that utilities want you to have a battery.
