We have deployed enough solar panels in the U.S. to power the equivalent of 2.2 million homes. Nationwide homeowners, small business owners, and retailers have already chosen Eagle Modules. We now add energy storage to the mix. Pairing solar with energy storage is an easy way to decrease the cost of owning a home or business. As you begin the process of selecting solar panels, insist on reliable, performance-proven Eagle Modules from JinkoSolar.
SOLAR & STORAGE 101
WHAT TO EXPECT
Home and business owners add solar and energy storage to save on electricity bills, cut operating costs, and lock in energy rates. Start by learning some basics that can help you decide whether solar and energy storage are right for you.
HOW THEY WORK
Solar panels generate DC power when exposed to sunlight. They are mounted on your roof with racks and paired with an inverter or several microinverters, which convert the DC power into AC power that your home or business can use. Energy storage systems use batteries, which store energy generated by the grid or by solar panels. These batteries can be installed in your garage or on the side of your house and are paired with an inverter which converts the power to AC power that your home or business can use.

WHERE THEY WORK BEST
Solar works all over the country for homeowners and small businesses, but it’s especially popular in areas with great sunshine or good local incentives. States with net metering allow your meter to spin backward as your solar panels generate more electricity than you use. You only pay the utility what’s left on the meter. Learn more about net metering. Energy storage systems can backup critical loads in your home or business. When the power goes out, the energy storage system kicks in to provide power to critical things like refrigerators or air conditioning. In some areas, there are high demand charges from the utility, or rates that peak at certain periods (time-of-use rates). The energy storage system can store energy generated by solar in the middle of the day when utility rates are low, then discharge that energy when rates are high, so you are not using the utility’s expensive power at that time.
THE EFFECT OF SHADE
Shade will definitely impact solar panel performance, though our new half-cell technology mitigates the impact of shade and still allows the solar panels to generate a lot of power. Energy storage relies on solar or the grid to power the batteries, so it too is affected if the solar system is underperforming. Physically however, energy storage systems are installed in a garage or a shaded area outside away from direct sun to protect the longevity of the batteries.
New solar systems come with rapid shutdown devices which ensure that the system turns off in emergencies such as fires. As the only energy generating device that requires no movement, solar systems are very safe and require little maintenance. Energy storage systems mostly use lithium ion batteries. These batteries come in several chemistries, including NMC and LFP. NMC is often seen in electric vehicles due to the compact nature of the batteries but have higher risk of thermal runaway. We use LFP, which is slightly larger but widely seen as a safer option. In addition, we have robust software embedded in the system which monitors and protects the battery’s state of charge and health.
The solar panels come with a standard 25-year power warranty and retain a high percentage of power at the end of the warranty. Recent data suggests these panels will function well beyond those 25 years. The panels are very durable and are effective at withstanding heat, hail, ice, snow, wind, and salt mist. We also have a strategic relationship with DuPontTM to ensure 100% of our panels are protected using extra-durable Tedlar® film. This film is used in the International Space Station and commercial jetliners, so it is very tough. Batteries don’t last quite as long, but we do offer a 10-year warranty, which covers the batteries and all other complementary components in the system. Many manufacturers cover only parts of the energy storage system, whereas we are solely responsible for everything.
The systems are not inexpensive. They can run tens of thousands of dollars. However, you will save a lot and payback periods can be as few as 3-4 years depending on where you live. How much you will save depends on the size of your systems, your current electricity prices, and local incentives. For energy storage, many areas prone to natural disasters have exceptionally high incentives which pay for a high percentage of the system. In many cases, due to the federal investment tax credit, which is currently 26% of the value of the solar and storage systems, you may save a lot on your taxes the following year. The value of the backup power from energy storage is hard to measure, but during power outages, keeping your refrigerator cold may be worth everything. Don’t wait too long, because the tax credit steps down to 22% in 2021 and will zero out in 2022. Our installers will outline these savings during the quotation process.

Today’s buyers demand intelligent, intuitive homes. In addition, a new California mandate requires every new home to have solar by 2020. People are seeking a more efficient lifestyle. That might mean living small or living smart. We have partnered with Green Builder Media and Innovative Home Builders to demonstrate solar powered next generation living.
Shelter Dynamics features two small-footprint, intelligent, net-zero, and sustainable homes, beginning with its two existing prototypes: the Flex House and the Arc House. The Arc House combines the economy and simplicity of small footprint living with cutting-edge building science. Smart, self-sufficient, and compact, the net-zero home integrates many facets of sustainability into one compelling and beautiful package. The Flex House is a model for “right-sized” living in a small, flexible space that is connected, intelligent, resilient and sustainable. The Flex House boasts an integrated smart + solar system as well as water-conserving products and fixtures and non-toxic, sustainable materials to ensure healthy indoor spaces.
