High-power range review
How should a 570–710W photovoltaic module range be selected?
Compare the published 570–590W, 605–625W and 690–710W Sunhorn models without treating wattage as a universal ranking.
Short answer
The published options differ in power, efficiency, format and weight. Start with SH18-72H-D, SH21R-66H-D and SH21-66H-D as distinct models, then test each against layout, electrical design, logistics and commercial requirements.
High-power range review
SH18-72H-D · 570–590W
Published maximum efficiency is 22.8%; dimensions are 2278 × 1134 × 30 mm and weight is 30.5 kg.
SH21R-66H-D · 605–625W
Published maximum efficiency is 23.2%; dimensions are 2382 × 1134 × 30 mm and weight is 32.5 kg.
SH21-66H-D · 690–710W
Published maximum efficiency is 22.8%; dimensions are 2384 × 1303 × 35 mm and weight is 38.5 kg. Its larger listed format requires its own layout and handling review.
Translate rated watts into a quantity basis
A hypothetical 1MWp request illustrates quantity rounding; it does not establish an available Sunhorn power bin.
| Field or step | Example entry or evidence to record |
|---|---|
| Assumed rating | Use 580W per unit only for this calculation: 1,000,000W / 580W ≈ 1724.14 units. |
| Whole-unit rounding | 1725 units × 580W = 1,000,500W = 1.0005MWp of nameplate DC capacity, not AC output or annual energy. |
| Commercial confirmation | Request the exact model, bin availability, permitted mixed bins, packing quantity, spare-unit basis and final count in the quotation. |
Illustrative arithmetic only. These assumptions are not Sunhorn product data or an approved system design; apply the exact documents and qualified project review.

FAQ
Frequently asked questions
Is 710W automatically the best option?
No. It is the highest listed power in this shortlist, but format, weight and system fit still matter.
Can these models be substituted directly?
No. Their dimensions, weight and electrical parameters differ.
What should be compared first?
Compare exact project layout and electrical boundaries before moving to logistics and price.
