Your estimated JPS savings

What you could save on your light bill with this solar system.

Each month
About J$4,600
Each year
About J$55,200

Estimated electricity use: about 134 units per month.

For the appliances you selected. A unit is shown as “kWh” on your JPS bill.

Solar could cover about 119 of those units each month.

A guide, not a promise. Savings depend on sunshine, when you use electricity and JPS rates. Fixed JPS fees still apply. The yearly figure assumes similar use and rates all year.

Have your JPS bill? Add details (optional)

Leave these blank for our estimate. Bill details only adjust this savings guide; your appliance choices still size the system.

Use this month's charges, without any old balance. We keep an allowance for fixed fees.

Look for “kWh” or “consumption” on your bill. A typical month works best.

How we estimate this

We use rounded planning costs of J$35 per unit for the first 100 units, then J$50. These are reference costs, not today's exact JPS rates. With batteries, we allow for 80% of estimated solar output to be used at home; without batteries, 40%. Actual use can differ. We count only electricity used at home, with no credit for selling power to JPS. If you add charges, we keep J$650 aside for fixed fees; your actual fees may differ.
