The typical solar system is designed to supply energy while the electric grid is running and switch off when the grid does not work. If you want to have power even in a situation when the grid goes down, you need additional equipment like battery storage. Every home has different needs so if you are looking for backup power, it’s crucial to choose the most suitable system. We’ve put together what we think are the best emergency power systems to ensure your home or business still has power during a power outage.
Lithium-ion Battery Systems
There are many solutions available on the market. Lithium-ion battery systems, which are one of the most expensive options, average about $30,000 to back up an entire house and an average $15,000 to power basic devices such as refrigerators or washing machines. Unfortunately, this solution can work only for one day during bad weather because Lithium-ion battery systems need routine energy supply from the sun to recharge the battery.
For residents who need necessary load backup at a reasonable price, portable generators can be a suitable emergency power supply option while the grid is unavailable or inaccessible. Portable generators can back up larger devices like dishwashers, refrigerators and sump pumps for approximately two to three days and may work even longer, but you will need more fuel. Portable generators are not only easy to operate, but also reliable and the most cost-effective solution.
Another one of the more cost-effective options is a standby generator which can provide your whole home with backup power for a very long time and it costs around $10,000. This option is great value, which can back up essential loads for the more useful appliances in your house at a lower price. Standby generators can operate regardless of weather conditions, so there is no need to worry about powering your home during a blackout. Generac’s line of standby generators are a popular option, with about 70% of homeowners choosing them for their emergency power needs.
Homeowners who only want to charge essential electronics like watches, phones or tablets and don’t want to waste money on large storage systems can use solar technologies too. SMA’s Secure Power Supply only costs about $500, but it turns off if solar production is too low. But solar homeowners have better options too. To charge small electronics in your residence, the best solution is a portable battery such as the Goal Zero Yeti. The Yeti costs $400 or less and can provide backup power 24/7. This option is not tied to whether the grid is running or not, instead it draws power from a portable solar panel or an electrical outlet and stores enough power for about three days of charging.
Taking everything into consideration, possessing solar panels and one of these emergency power systems lets you remain independent and have your own power station during power outages. For more information call Solartime at (972) 675-7725 or contact us online!
