As solar energy becomes increasingly popular, many homeowners are considering whether to include a battery in their solar system purchase. While batteries can offer significant benefits, they also come with additional costs and complexities. In this blog post, we’ll break down the key factors to consider when deciding whether a solar battery is right for you.

1. Energy Independence

One of the primary benefits of a solar battery is increased energy independence. With a battery, you can store excess energy produced during sunny days and use it during cloudy periods or at night. This reduces your reliance on the grid and can provide peace of mind during power outages.

2. Electricity Costs and Time-of-Use Rates

If your utility company charges higher rates during peak hours, a battery can help you save money. You can store energy when rates are low and use it during peak times, potentially reducing your electricity bills significantly.

3. Environmental Impact

By storing and using more of your own solar energy, you’re reducing your carbon footprint. This can be particularly impactful if your local grid relies heavily on fossil fuels during peak hours.

4. Initial Cost

Solar batteries represent a significant upfront investment. While prices have decreased in recent years, they still add substantially to the overall cost of a solar system. It’s important to calculate the potential savings over time to determine if this investment makes financial sense for you.

5. Available Incentives

Many regions offer incentives for solar battery installations, such as tax credits or rebates. These can help offset the initial cost and make batteries more attractive. Research the incentives available in your area.

6. Your Energy Consumption Patterns

Consider your daily energy usage patterns. If you use most of your energy during the day when your solar panels are producing, a battery might be less beneficial. However, if you consume a lot of energy in the evening or at night, a battery could be very useful.

7. Grid Reliability

If you live in an area with frequent power outages, a battery can provide valuable backup power. This can be especially important if you have critical medical equipment or work from home.

8. System Complexity and Maintenance

Adding a battery increases the complexity of your solar system. This means potentially more maintenance and a higher likelihood of technical issues. Consider whether you’re comfortable with this added complexity.

9. Battery Lifespan and Warranty

Solar batteries typically last 10-15 years, which is less than the lifespan of solar panels. Factor in the cost of potential battery replacement when making your decision. Also, compare warranty terms among different battery options.

10. Future Energy Plans

Think about your future energy needs. If you’re planning to purchase an electric vehicle or increase your electricity usage in other ways, a battery might become more beneficial over time.

Conclusion

While solar batteries offer numerous benefits, they’re not the right choice for everyone. By carefully considering these factors and consulting with a solar energy professional, you can make an informed decision about whether to include a battery in your solar system purchase. Remember, the goal is to create an energy solution that best fits your specific needs and circumstances.

We wanted to understand all the factors at play, and have investigating this: the answer is that the break even on a medium size commercial building (e.g. a 3,000 m2 roof such as Markian House), have been falling consistently for almost ten years, and are now lower then they have ever been. This is owing to a combination of (a) the plummeting cost of solar panels, (b) the grid import price of electricity increasing, and (c) the export price of selling into the grid increasing. This chart combines all these factors to model the break-even point:

To elaborate on these factors:

1. Solar panel price: since 2010 the cost per Watt of a solar panel has dropped by 90%. The larger the solar installation, the higher proportion of the cost is solar panels, given other costs are fixed or semi-fixed. This trend of price decrease has been consistent since 2010 and so the costs of large solar projects have fallen commensurately.
2. Import price of electricity: The biggest saving from solar is from self-generating electricity. In 2022, the price of electricity more than doubled. Although it has now come down moderately, it is still over twice the average of during the 2010s (and the price cap increased today). With the prices of electricity increasing so much, it makes the returns from solar much better as you’re offsetting a higher p/kWh with free solar electricity
3. Export revenue of electricity: In the 2010s, the government provided the Feed-In-Tariff (FiT) which paid “generators” per kWh for the solar electricity they generated. This is why in the chart, despite panels being 10x more expensive in 2010, the breakeven was only 8 years. The FiT tariff was very generous and so the government reduced it until it was pretty negligible by 2015-17 (e.g. 40p/kWh in 2010 to about 2-3p/kWh in 2016). Hence why the breakevens were so high in that period of >15 years). However, since 2020, the Smart Export Guarantee that replaced it has been increasing, due to point #2, and has contributed to the break-even time decreasing.

With these factors combined, the break even on a commercial building of the size of Markian House is extremely good at well below four years.

As such, for a tenant on a 8+ year long term lease, it would make sense for them to install solar. Even if they moved out at the end of the lease, they would still have four years of generating electricity for free after they’ve fully paid for the system.

We are currently in an unprecedented “sweet spot” for medium-to-large commercial solar installations. This is something that not many companies have realised yet, but it makes for a very compelling overall proposition.

In a groundbreaking achievement for renewable energy, a new world record for solar panel efficiency has been set, marking a significant milestone in the quest for sustainable energy solutions. This leap in technology not only highlights the rapid advancements in the renewable energy sector but also brings practical benefits to everyday consumers, including potential savings on energy bills.

A New Benchmark in Solar Efficiency

Researchers have shattered the previous efficiency records by developing a solar panel capable of converting more sunlight into electricity than ever before. This innovation means that solar panels can now generate more power from the same amount of sunlight, making them more efficient and cost-effective.

What This Means for You

1. Lower Energy Bills: With more efficient solar panels, homeowners and businesses can generate more electricity on-site, reducing reliance on traditional power sources and lowering monthly energy bills.
2. Faster Return on Investment: The increased efficiency of these new panels means that the payback period for solar installations is shorter. You start seeing savings sooner, making the switch to solar an even smarter financial decision.
3. Environmental Impact: More efficient solar panels contribute to a reduction in greenhouse gas emissions. By harnessing more power from the sun, we can decrease our dependence on fossil fuels and move closer to a sustainable future.

Act Now and Save

There’s never been a better time to invest in solar energy. With the latest advancements in solar panel technology, you can take advantage of:

• Government Incentives: Many regions offer tax credits, rebates, and other incentives for installing solar panels.
• Increased Property Value: Homes equipped with solar energy systems often see a boost in property value.
• Energy Independence: Reduce your vulnerability to energy price hikes and supply disruptions.

By making the switch to solar energy, you’re not just saving money; you’re also contributing to a cleaner, greener planet. Embrace the future of energy today and start benefiting from the most efficient solar technology ever developed.
