Frequently Asked Questions
How long will my solar power system last?
All of the equipment we use comes with a 25 year warranty. The panels we use have all lasted well beyond their warranty period. All panels will degrade at about .5% per year.
How can I tell how my system is performing?
All of our systems include lifetime monitoring. You will be able to look online or download a convenient mobile app to monitor your system production. Sungenia also monitors your system and will send you updates and notifications if necessary.
What maintenance does the system require?
Dirty panels can decrease production. Usually only by a few percent, but in the case of persistent buildup over a long period of time the production can degrade considerably. In general, PV modules do not need much in the way of cleaning, however, in this part of the country we don’t get a lot of rain so cleaning is sometimes necessary. If you feel that you’d like to clean your panels use the following guidelines:
- Clean in the morning, if possible, before the panels start heating up. If you have to clean them while they’re hot, mist or lightly spray them first to cool them down before cleaning.
- Wash the modules using plenty of water (tap water or deionized water) without any cleaning agents.
- If necessary, a soft cleaning device (sponge or soft brush with split bristles) may be used.
- In case of soiling by dust or sand the modules can be cleaned with a soft brush without using water.
- Never scrape or rub off dirt; this may result in micro- scratches.
- Don’t stand in pools of water while cleaning; remember, the panels are still producing electricity.
If you’d rather not clean them yourself, almost any window washing or specialized solar panel cleaning company will have the best equipment to do it for you.
Will a system produce enough energy to cover all my electricity needs?
Every house is different, and we design your solar system based on your specific needs. Whether you want to produce 50% or 200% of your current bill, we can do it.
How many solar panels do I need to produce enough electricity to run my house?
Every house is different. We’ve seen $50/month bills, and we’ve seen $5,000/month bills. How many solar panels you need is entirely dependent on your usage and the type of panels that are determined best for your house. An approximate guideline for our systems:
- $100/mo electricity bill – 3 kW system
- $300/mo electricity bill – 6 kW system
- $500/mo electricity bill – 9 kW system
- $700/mo electricity bill – 12 kW system
What is net metering?
Net Energy Metering, or NEM, is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. For example, if a residential customer has a PV system, it may generate more electricity than the home uses during daylight hours. That credit can be used to pay for the energy that you use at night.

Do I need approval from my homeowners' association?
Most HOA’s will require a submittal and approval before we can start work on your house. Many have very simple processes and are easy to work with, others have more strict requirements. You will need to send us the HOA guidelines so we know what paperwork and information is required.
