BATTERY FAQ

We answer the most frequent questions about solar battery storage that customers ask our consultants.
Solar panel, solar inverter and solar system frequently asked questions are covered on our Solar FAQ Page.

Are Solar Batteries Worth It?
The payback time for a solar system with a battery is longer then for just solar panels. Batteries do pay for themselves and can reduce or eliminate power bills and avoid power bill shock.Solar batteries also have other benefits that are not quantifiable in financial terms that battery customers gain advantage from, including:

  • Gaining energy independence
  • Protection against blackouts
  • A lower carbon footprint

For a more in-depth look at the advantages of a solar battery refer to our page Why Install a Solar Battery.

Do solar batteries protect against blackouts?
Most solar battery storage systems can be configured to provide protection against power interruptions. This ability is not automatically available with all batteries and may require specific configurations and options for the solar battery system. Please discuss with your SolarBright consultant if you require blackout protection with your solar battery.
Can I be power bill free with a solar battery?
A combination of a correctly sized solar system and solar battery can reduce your bill to nearly zero.  All of the solar systems SolarBright install are grid connected so even if the solar panels and solar battery storage covers all of your power requirements your energy provider will still be charging you a network access fee and the feed in tariff from your power exports may cover that.
How does a solar battery work?
A solar battery works by storing the excess power your solar panels generate, and you don’t consume, for use later or at night. Most batteries use lithium-ion based battery cells to store the electrical power, and the Tesla Powerwall 2 and LG Chem use Nickel Manganese Cobalt (NMC) which is compact and lightweight.
Can I monitor the solar battery?
All the batteries that SolarBright install have battery management software and phone-based apps that can monitor the solar battery and help manage the battery and your battery power consumption. As solar battery owners become more aware of their power usage patterns, they adjust their consumption and behaviour to increase their energy independence.
Can I add a battery to my existing solar system?
In most cases the answer is yes. If your system is several years old, you may have to replace the inverter with one that can manage a solar battery. Organise an obligation free consultation with a SolarBright consultant for a free assessment of your current system and expert advice on what your best options are or give us a call.
What are the warranties on solar batteries?
Most solar battery manufacturers warranties cover ten years or a certain number of battery cycles, whichever comes first, for example 10 years or 6000 cycles. Over ten years 6000 cycles equates to 1.6 battery cycles per day.
What is a battery “cycle”?
A battery cycle is the equivalent a of full power charge and full discharge of the battery. Partial charges and partial discharges are not considered a full cycle but count toward a full cycle. So if one day your solar battery is fully charged and you use 60% of the battery that night, then it is fully charged again the next day and you use 40% of the battery the next night, the 2 discharges of 60% and 40% and battery charges add up to 100% or one solar battery cycle.
Can I increase my battery storage capacity in the future?
Yes. There several factors to consider. The most important question to answer is your solar system producing enough excess energy to charge another battery or will you need to add more panels to generate more power?

The Tesla Powerwall has a capacity of 13.5kWh so extra capacity can only be added by installing a second battery of the same size.

The Triple Power solar batteries come in a 4.3 or 6.5kWh capacity. Once you have installed a battery you can add up 3 more batteries of the same size as the original battery in an almost plug and play fashion with the same inverter.

What solar battery brands does SolarBright install?
SolarBright has extensive experience with solar batteries. We are a Tesla certified Powerwall Installer, and also install solar battery systems from Triple Power and LG Chem.

Customer Reviews

  • 'Solar Bright sales person Roy was the main reason for installing the solar panels at home, he is a very courteous & patient person, who had professional answers to my queries. The panels were installed 1 week earlier than anticipated. The whole installation was done by the end of the day. The system is working very good. Thanks Roy & all the personnel @ Solar Bright.'

  • The whole process was simple and fast .Javier came to our house and showed us the design and explained the process . Once I said yes to them ,within a week installation process done. Very impressed! My concern was there are so many cheap installers but I first checked with LG company to get the their authorised dealer and SolarBright is one of them. That's enough for me to trust this company.

    Renju

  • SolarBright were great to deal with, very efficient company, Installers were polite and did a brilliant job, without any fuss. The new MaxBreeze Zhas shown excellent results in a very short time, we could feel the difference almost immediately with the sensors we have in our ceiling. I have no hesitation in recommending this product to family and friends. Once again thankyou to SolarBright for a professional job well done.
