Grid-tied solar without batteries in Las Terrenas

Who it is for

The Grid-tied, no battery package suits shops and buildings that are mainly occupied during the day:

• shops, convenience stores, offices, workshops, clinics and schools;
• businesses with refrigeration or air conditioning running during opening hours;
• homes with high daytime consumption, when outages are not the main concern.

It is the option that aims to lower the bill with the smallest investment, because it has no batteries. In return, it offers no backup during power outages.

How it works

The setup is direct: panels → grid inverter → electrical panel → appliances on site.

1. During the day, the panels produce direct current and the inverter converts it into alternating current, the kind your equipment uses.
2. That energy is used first on site: it is electricity you no longer buy from the utility.
3. If production exceeds consumption, the surplus is fed into the grid, or limited if the system is set up not to export.
4. At night, all the energy comes from the grid, as before.
5. During an outage, the inverter shuts down automatically. This is a standard safety protection: the system must not send power into a grid where technicians may be working. That is why a system without batteries gives you no power during outages, even in full sun.

What the package usually includes

Power is defined after the technical visit, based on your daytime consumption. A Grid-tied, no battery package usually includes:

• solar panels and their mounting structure;
• a grid-tied inverter;
• protection devices, wiring and connection to the electrical panel;
• production monitoring, when the equipment allows it;
• installation, commissioning and an explanation of how the system works.

Manufacturer and installation warranties are specified in the quote.

Net metering: what needs to be checked

In the Dominican Republic there is a net metering program (medición neta) that, under certain conditions, allows energy fed into the grid to be taken into account on your bill. The conditions, procedure, meter type and timelines depend on the rules in force: they must be checked with the distribution company (EDENorte for Samaná province) and, if needed, with the SIE or the CNE. We do not promise eligibility.

Until those conditions are confirmed for your case, the prudent approach is to size the system so that most of the production is used on site. More details in the net metering guide.

Benefits and limitations

Benefits

• The lowest investment among solar solutions, since there are no batteries.
• A simple system that needs little maintenance.
• Well suited to consumption that coincides with sunshine hours.

Limitations

• It does not work during outages.
• It produces nothing at night.
• The value of the surplus depends on net metering rules, which must be checked.
• Adding batteries later is only possible if the inverter allows it, or by changing equipment.

What we check during the technical visit

• Your consumption and schedule: bills, opening hours, equipment that runs during the day.
• The roof: type, condition, orientation, available area and shade.
• The meter, the electrical panel and the type of connection (single-phase or three-phase).
• The location for the inverter.
• The impact of outages on your business: if they are critical, a hybrid system or a business study may be more suitable.

Can I add batteries later?

Sometimes. It depends on the inverter chosen. If you think you may add batteries in the future, tell us from the first contact so we can take it into account in the proposal.

How much could I reduce my bill?

It depends on how much of your consumption happens during sunshine hours. The solar calculator gives you an indicative estimate; the quote is based on your actual data.
