Here are a few of the questions we get asked about our systems and services. If you need more information, please Contact Us and we’ll be glad to help!

We can do that together. Best is to start by calculating your daily electrical needs or to check your utility bill if you already have one.

Yes we can install a back-up system on your property and you can use both. This is the best solution. We call it “grid assist” and you can learn more about it in this video from Outback.

Some do, some do not… And some say they do, but give very little! Check with your local government to see what is their policy.

In the Caribbean, the best roof installation should be facing due south and tilted in degrees equal to their latitude (15° for Dominica).

Sustainable Earth Inc. will install your system with you and/or your electrician. It is important for you to understand how it works. We can sell the system with cables pre-cut and with lugs installed , under the DIY program. Very useful when you are outside of Dominica.

You should consider Sustainable Earth Inc. as your 1st choice provider for alternate energy systems for 3 main reasons:

    1. We are based in the Caribbean, live and work here and have tested the brands and systems we promote in the real Caribbean environment. As an example, we know our sealed Victron and Outback Inverters are the best choice for the harsh Caribbean environment. We know some solar panels cannot withstand the sea blast , same for some charge controlers or inverter. All material is not manufactured with the same standards, the same quality of raw material.
    2. We offer a follow up and maintenance/warranty locally; Not from a hotline in the USA or Europe.
    3. We represent the world leader brands in the Caribbean. They might not be the cheapest available on the market, but they have shown they work for years and have proven being reliable.
  • We can quote in 24 hours.
  • Refine the exact sizing and material/installation choice within 1 week.
  • Deliver immediately from our inventory in Dominica, or about 3 weeks later if not in stock.
  • Then install in 1 week. Total 2 to 5 weeks.

If you are not grid connected, we recommend you to seriously consider any real low energy appliances (such as refrigerators, freezer, light bulbs, washing machine) and to avoid A/C by designing a well ventilated house.

If you are grid connected, we recommend to install a backup system first from our available kits to provide energy to your sensitive electronic equipment and to have all absolutely necessary appliances working in the event of your utility company power failure (refrigerator, phone charger, lights).
