About Us

Solar systems differ according to purpose and capacity, but all solar panels have these five basic components:

• Solar Panels – Photovoltaic modules assembled in a frame to capture energy from the sun.
• Solar Inverter – A device that converts the energy captured by the solar panels from direct current (DC) to alternating current (AC), which is the standard current required to power our appliances.
• Mounting System – Also called racking, this system holds your solar system equipment in place in an installation.
• Batteries – Battery-based solar systems require batteries to store the energy generated through the solar panels.
• Charge Controller – Also known as battery regulator, this device regulates the flow of current to and from the batteries to prevent overload, overcharging and overvoltage.

Apart from the main components above, other smaller components like meters may also be found in a solar system depending on the model.

Our solar panels are warrantied for 25 years, so that should be your benchmark for the system's lifespan. However, you should expect to replace a few other parts along the way. Below are our warranty periods for some of our solar system components:

• Grid-tie String Inverters – 10 to 15 years
• Off-grid Inverters – 5 to 10 years
• Batteries – 1 to 10 years (varies widely depending on technology and model/manufacturer)

Note: When considering lifetime cost of ownership, be sure to account for scheduled part replacements along the way.

Yes, it is possible if you have the skill and experience. However, it is advisable to get a state-of-the-art installation done by our certified engineers who will install your solar system in the most efficient way to guarantee maximum satisfaction and safety.

If you are currently using a GreenSource solar system, you might receive two bills:

• GreenSource Energy Plan Bill – This bill covers your lease or loan financing agreement or Power Purchase Agreement (PPA) with GreenSource. This bill will be sent to you monthly and is expected to be paid by the specified due date.
• Utility Bill – Clients who are subscribed to a GreenSource solar system in addition to other existing utilities (e.g., grid-based electricity provider) will receive an additional bill from the relevant company.

Your GreenSource solar system is connected to your existing utility. At night and during times of low solar output, you may need to pull electricity from your utility to meet your energy needs. However, using your GreenSource solar system as your primary source of energy can help to reduce your utility bill.

Your utility’s net metering policy outlines the terms and conditions that govern your connection to the grid. It dictates the rates you are charged or credited for power bought or used from the grid. Understanding your net metering policy is key to figuring out what kind of return you can get from your investment in solar.

To figure out your savings from solar, it will take a little math and some data collection. We recommend comparing a full year of utility and solar system bills in order to account for seasonal changes.

1. Look at your utility bills from the 12 months before you went solar.
2. Look at your utility bills from the 12 months after you went solar plus the corresponding 12 months of solar system bills.
3. Compare the pre-solar system utility bill with the matching post-solar system utility bill for the same month.
4. We also recommend looking at the full year pre-solar system versus the full year post-solar system.

If you’re a GreenSource customer, your solar system will be custom-built to meet your energy needs. If you start using more energy or if you make large modifications to your residence or workspace (like installing a pool or charging an electric car), your energy needs and associated costs will change.
