Stop selling your Excess Solar Power for 1 - 5 cents!!!

Did you realise that your Energy Retailer is buying your excess solar off you for 1 - 5 cents per kWh and selling it to your neighbours for 30 - 35 cents per kWh?

In the last month most homeowners would have received an email or letter from their Electricity retailer stating that prices are going up 20-35%. They have also been told that solar feed in rates have dropped from 10-20c down to 1-5c per kWh.

We have had quite a lot of customers fed up with these changes and this has made them look at purchasing a battery to store their power instead of selling it for 1-5c.

Here is a list of frequently asked questions we get.

How long does a battery last?
The lifespan of solar batteries varies depending on the type, brand, and usage. Most batteries have warranties that range from 5 to 15 years, but with proper maintenance and usage, their lifespan can extend beyond the warranty period. Lithium-ion batteries, which are commonly used in solar energy storage, are known for their durability and longevity.

Can a solar battery power my entire home?
The capacity of a solar battery determines how much electricity it can store and provide. The size of your solar panel system and household electricity consumption also play a role. While a solar battery can power essential loads or parts of your home during power outages, powering the entire home continuously may require multiple batteries or a larger capacity system.

Can I add a solar battery to my existing solar system?
In most cases, it is possible to add a solar battery to an existing solar panel system. However, compatibility and system integration issues should be considered. It is recommended to consult with an iinergy solar professional to assess your specific setup and determine the best options for adding a battery.

Are there any government incentives or rebates for solar batteries?
The availability of government incentives or rebates for solar batteries varies depending on your location. In some places, there may be federal, state, or local programs that offer financial incentives or tax credits for solar and energy storage installations. It is advisable to check with or consult a solar professional to explore potential incentives in your area.

How much does a solar battery cost?
The cost of a solar battery can vary widely based on factors such as capacity, brand, and installation costs. On average, a solar battery system can range from a few thousand dollars to tens of thousands of dollars. However, it's important to consider the long-term financial benefits and potential cost savings in electricity bills when evaluating the overall investment.

iinergy has battery packages from as little as $25 per week.
