10.Your original system did not eliminate 100% of your bill in the first place.

9. You have added electric appliances, so your energy bill has increased.

8. You have added an electric car, so your energy bill has increased.

7. More people living in your household, so your energy bill has increased.

Solar inverters typically last 10-12 years before needing replacement.

6. Lock into more solar before utility solar fees increase AGAIN.

5. Updating is a lot cheaper than replacing, since the panels are good for 25 years.

4. Your PG&E rate plan has changed, increasing your bill.

3. You want the advanced system functionality.

2. Off-peak energy rates have increased 100% in the last 10 years.*

1. Inverter is at the end of its useful 10 to 12-year lifespan and prone to failure.


A solar energy system upgrade ensures you get the maximum return from your initial solar energy investment.

There are many options when it comes to upgrading your existing solar energy system. Typically the inverter is the primary upgrade component. Most inverters have a 10-year warranty, and tend to fail shortly thereafter. Older inverters also did not have a monitoring component, or other more advanced technology to optimize performance. Today's inverters monitor and optimize individual panel performance.

If your original system only eliminated a portion of your energy bill, you can also add a few more high-efficiency solar panels to bring your energy production up, and bring your bill down to zero.

* It is pretty challenging to develop a forecast for TOU plan rate increases, because there are a lot of different prices to consider: peak hour, off-peak hour, part-peak hour, summer versus winter rates, baseline and over baseline charges, and so on. Another factor making historical analysis difficult is the fact that PG&E has dropped some popular rate plans, such as their E-7 TOU plan, while rolling out others, like their E-TOU-A and E-TOU-B plans.

But PG&E has continually offered the E-6 TOU plan since 2008, which gives us a long-term trend to analyze: The PG&E E-6 plan’s off-peak summertime rates have more than doubled, from 8.5 cents in 2008 to nearly 18 cents in 2019. Meanwhile, their peak rates have also increased, from 29.3 cents to 37.1 cents. The off-peak rate increased by over 100% in 11 years, while the peak rate increased by 26.6%. The average yearly increase was 7.1%. This means that if your electricity bill is currently $300, we would expect you to pay about $596 per month in 10 years, and nearly $1,200 per month in 20 years. To look at it another way, a $300 bill today was only $150 10 years ago.
