The essentials
Before you buy.
Is US$5.99 a monthly subscription?
No. It is one payment for 30 days of access. There is no automatic renewal or recurring charge.
What will I receive?
Private access to the English-language MEDELAPP Solar International calculator. It estimates solar capacity, panel quantities, inverter requirements and battery capacity from the inputs you provide, with print / save-to-PDF output.
When do I get access?
After the payment team confirms your payment, your account is authorized and access instructions are sent by email. This page does not promise instant or automatic activation.
Do I need to provide technical information?
You need your electricity consumption and a solar-resource value. Optional NASA POWER retrieval can supply a screening value for the selected city. For battery configurations, provide the simultaneous backed-up load and starting surge. Actual battery module ratings can replace the editable planning assumptions.
Does this replace an installer or an electrical design?
No. Results are preliminary. A qualified installer must validate site conditions, local requirements, equipment compatibility, protection, wiring and actual performance before you buy or install equipment. Generation and savings are estimates, not guarantees.
