Read guideThe shortest answer: choose grid-tied solar when the goal is mainly to reduce grid electricity use; choose hybrid when selected loads must continue through outages; and choose off-grid when there is no dependable utility connection. A marine system is a separate application that must integrate with a vessel's existing batteries and charging equipment.
A grid-tied inverter works with the utility supply and normally stops during a grid outage for anti-islanding safety. It is often the simplest architecture where a stable grid is available and backup is not required.
A hybrid design combines solar, battery storage, and the grid or a generator. Decide which circuits need backup and for how many hours before selecting a battery; backing up every load can change the design and cost substantially.
An off-grid system must supply the site's loads without relying on a utility. Load measurement, nighttime use, cloudy-weather autonomy, generator strategy, and future growth matter more than a generic package label. Use our system comparison table as a starting point.
A useful solar proposal starts with evidence about the site and its energy use. Send what is available; missing items can be confirmed during the assessment.
A final proposal should identify equipment, assumptions, exclusions, warranty terms, expected production, project scope, and the basis of any savings estimate. Start with our solar quotation form.
Net metering measures electricity imported from the grid and electricity exported by an approved solar system. The applicable approval process, capacity limit, meter arrangement, export treatment, documents, and billing method depend on the current regulator and utility requirements for the island.
Before treating exported energy as part of a financial estimate, confirm that grid capacity is available, the proposed system is eligible, and the current utility terms have been used. Solar consumed directly at the property and solar exported to the grid may have different financial value.
A standard grid-tied system does not normally provide power during a utility outage. If outage operation matters, the proposal should identify a hybrid or backup architecture and the circuits it will support.
Commercial solar design begins with when electricity is used, not only the total monthly bill. Daytime demand can often use solar directly, while evening loads, backup requirements, and generator operation may justify a different architecture.

A vessel solar system is constrained by usable area, moving shade, salt and moisture, vibration, wind loading, cable routes, and the existing DC electrical system. Begin with the daily energy needed for lighting, electronics, pumps, navigation equipment, or other intended loads.
Confirm the vessel's battery chemistry, nominal voltage, capacity, charging sources, and allowable charge settings before choosing a controller or inverter. Mounting must remain secure without creating unsafe obstructions, damaging the vessel, or placing equipment where water can collect.
The quotation should identify which loads the solar system is intended to support and what performance assumptions were used. View Ecogreen Maldives' documented dhoani project experience and marine solar service scope.
A long warranty headline is not enough. Read the written terms for the exact model and separate the parties responsible for each part of the system.
Ask for model numbers, datasheets, warranty documents, environmental ratings, compatibility, and local support terms before approval. Our solar basics guide explains the difference between product and performance coverage.
