If you are a homeowner seriously considering solar, the process is more straightforward than it might appear. Here is a practical end-to-end guide.
Step 1: Understand Your Consumption
Gather 12 months of APUA bills and note your monthly kWh consumption. Most households consume 300–600 kWh/month; those with pools, heavy A/C, or electric water heating may use 800–1,200 kWh/month. Consumption drives the appropriate system size.
Step 2: Get Multiple Quotes
Contact at least three local installers. A reputable quote includes system size in kW, panel and inverter models, estimated annual production, projected savings in EC$, warranty terms, and timeline. Use the Solar Calculator to verify projections.
Step 3: Verify Equipment Quality
Tier 1 panels (Jinko, Longi, Canadian Solar, Q Cells) with 25-year performance warranties. Proven inverters (Fronius, SMA, SolarEdge, Growatt) with local service support. In a small market, after-sales support matters.
Step 4: Arrange Financing and Get APUA Approval
If not paying cash, get pre-approval before finalizing your installer. ECAB, FirstCaribbean, and RBTT all offer relevant products. Grid-tied installations require APUA approval — your installer should handle the application. Do not begin installation without written approval.
Step 5: Install, Commission, and Register for Net Metering
Installation typically takes 1–3 days. After commissioning, register for net metering within 30 days to receive credits for exported power. Confirm your monitoring app is working before the installer leaves the site.
