FAQs
Have questions about solar?
You aren’t alone, here are some of the most common questions that we get. If you have other questions that aren’t answered here just send us a message!
What is the typical cost of a residential solar system?
The cost depends on the size of the system. A 10kW system, the typical system size, costs around $23,000 before applicable tax credits. This size system will offset up to 80% of the electric bill for an average-sized house. A 4kW system, a good option for a smaller house, costs around $9,800 before applicable tax credits.
What is included in the price I pay for the system?
- Consultation to determine the system requirements that best meet your needs.
- System design and engineering
- Solar panels, an inverter to convert DC power to AC power, and the applicable racking, hardware, and electrical materials. Components are made in the USA!
- Full installation and commissioning of the system
- Warranties for system components and installation workmanship
What is a typical rate of return on a solar installation?
Rates of return vary but returns in the 10-15% range are very common, and higher rates of return are sometimes achievable.
How many years to pay back a solar investment?
Typically, a cash purchase pays back in full by year 7 or 8.
What is the cost of adding a battery backup to a solar system and what are the returns for a battery?
Costs will vary, but the average cost for a critical load backup is as low as $3,000, and a whole home backup is as low as $7,000. Our backup systems can provide power for up to 2 days. A battery will pay for itself over its expected life, which is around 15 years.
How long does installation take once we decide to move forward?
We can usually start the installation process 6-10 weeks after approval. A standard installation can be completed in 2-3 days.
What are the maintenance requirements for solar?
Virtually none. If energy production is diminished due to an accumulation of dust, soil, or other debris on the panels, rinsing them off with water will restore full production.
What is the current battery technology and when will the next generation of batteries be available?
Currently, lithium iron phosphate batteries are best for solar storage because of their long life expectancy. We anticipate solid-state batteries will be available for residential systems by 2030.
What are the standard warranties for the solar panels, inverters, batteries, and installation?
Standard warranties we offer are:
- Standard solar module warranty – 25 years
- Inverter warranties – 10 years with extended warranties available for purchase.
- Battery warranties – 10 years
- Workmanship – Guaranteed for 5 years
What roof orientation is best for solar?
In the United States, a south-facing roof will be the most productive. However, east and west-facing roofs can be very productive, especially if the pitch is not too steep.
If I need to replace my roof, how much will it cost to remove and re-install my solar equipment?
A standard 10kW system will require 2 people and 2 days to remove and reinstall the rooftop components.
