The panel uses polycrystalline silicon cells, and the declared conversion efficiency is 19\u201322%. The open-circuit voltage is 45.3 V.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Allpowers foldable solar panel powering an Allpowers portable power station on a lawn\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24913\/32958\/1-569c9bd0-983a-4b49-8b90-5d84793344c7.jpg\" \/>\n<\/p>\n<h3>Foldable design for easy transport<\/h3>\n<p>The panel consists of five interconnected segments, allowing you to reduce its size after use and transport it more conveniently in a car or RV. An integrated handle makes it easy to carry, and adjustable legs allow you to position the panel at the optimal angle relative to the sun. This solution works well whether you\u2019re camping, at a summer cottage, in the garden, or during an extended stay off the power grid.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Allpowers solar panel and power station with a drone on rocky ground next to cars\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24913\/32958\/2-81c0b283-fd2a-4a5d-a270-68972d3af23f.jpg\" \/>\n<\/p>\n<h3>Rated power of 400 W and efficiency up to 22%<\/h3>\n<p>The rated power of 400 W allows the SP037 to be used to charge power stations with higher capacity. The voltage at maximum power point is 37.4 V, and the current is 10.6 A. The declared cell efficiency ranges from 19% to 22%, though the actual amount of energy generated depends, among other factors, on sunlight exposure, the panel\u2019s angle of inclination, temperature, and the degree of shading.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Black Allpowers solar panel with foldable support legs set up on the grass\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24913\/32958\/3-3a78171f-1d93-430a-a5f3-4b1e51fd6014.jpg\" \/>\n<\/p>\n<h3>MC4 Connectors and Extensive Connection Options<\/h3>\n<p>The ALLPOWERS SP037 uses MC4 connectors with a rated current of up to 25 A. This is a parameter of the connector itself\u2014the panel achieves a short-circuit current of up to 11.45 A. The included cables allow the panel to be connected to compatible ALLPOWERS power stations, such as the S1500, S2000, S2000 Pro, or R4000. For devices from other brands, check the required voltage, current, and solar input type before connecting.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Allpowers portable solar panel connected to a power station resting on a chair\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24913\/32958\/4-dbaa9325-24bd-4686-b5fc-844c284a0062.jpg\" \/>\n<\/p>\n<h3>ETFE Surface and IP67 Rating<\/h3>\n<p>The panel\u2019s surface is protected by an ETFE laminate, which safeguards the cells during outdoor use. The design is rated IP67, meaning it provides full protection against dust and resistance to brief immersion in water under specific test conditions. However, this rating should not be interpreted as a recommendation to operate the panel during heavy rainfall.<\/p>\n<p>\n<img decoding=\"async\" alt=\"A foldable Allpowers solar panel attached with a carabiner to the roof of a white RV\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24913\/32958\/5-fece19fe-0908-4ef1-9650-ede3b6ef2545.jpg\" \/>\n<\/p>\n<h3>For RVs, camping, and off-road use<\/h3>\n<p>The panel can be placed next to the RV or temporarily mounted on the vehicle while parked, allowing you to use the available space to charge the power station. It is not intended for use or to be left in this position while driving. Once charging is complete, it can be folded up again and prepared for further transport.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Water droplets on the waterproof surface of an unfolded Allpowers solar panel\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/24913\/32958\/6-7312bbbb-d145-4a71-b048-fb042d1d4b88.jpg\" \/>\n<\/p>\n<h3>Included in the set<\/h3>\n<ul class=\"list-disc pl-5\">\n<li>ALLPOWERS SP037 400 W photovoltaic panel<\/li>\n<li>MC4\u2013XT60 cable<\/li>\n<li>MC4\u2013DC cable<\/li>\n<li>User manual<\/li>\n<\/ul>\n<div class=\"table-wrapper\">\n<p>\u00a0<\/p>\n<h3><\/h3>\n<table>\n<tbody>\n<tr>\n<th>Manufacturer<\/th>\n<td>ALLPOWERS<\/td>\n<\/tr>\n<tr>\n<th>Model<\/th>\n<td>SP037<\/td>\n<\/tr>\n<tr>\n<th>Type<\/th>\n<td>portable, foldable solar panel<\/td>\n<\/tr>\n<tr>\n<th>Rated power<\/th>\n<td>400 W<\/td>\n<\/tr>\n<tr>\n<th>Power tolerance<\/th>\n<td>\u00b15%<\/td>\n<\/tr>\n<tr>\n<th>Cell type<\/th>\n<td>polycrystalline silicon<\/td>\n<\/tr>\n<tr>\n<th>Declared efficiency<\/th>\n<td>19\u201322%<\/td>\n<\/tr>\n<tr>\n<th>Surface lamination<\/th>\n<td>ETFE<\/td>\n<\/tr>\n<tr>\n<th>Open-circuit voltage (Voc)<\/th>\n<td>45.3 V<\/td>\n<\/tr>\n<tr>\n<th>Short-circuit current (Isc)<\/th>\n<td>11.45 A<\/td>\n<\/tr>\n<tr>\n<th>Voltage at maximum power point (Vmp)<\/th>\n<td>37.4 V<\/td>\n<\/tr>\n<tr>\n<th>Current at maximum power point (Imp)<\/th>\n<td>10.6 A<\/td>\n<\/tr>\n<tr>\n<th>Connector<\/th>\n<td>MC4<\/td>\n<\/tr>\n<tr>\n<th>Maximum MC4 connector current rating<\/th>\n<td>up to 25 A<\/td>\n<\/tr>\n<tr>\n<th>Protection rating<\/th>\n<td>IP67<\/td>\n<\/tr>\n<tr>\n<th>Number of segments<\/th>\n<td>5<\/td>\n<\/tr>\n<tr>\n<th>Adjustable supports<\/th>\n<td>yes<\/td>\n<\/tr>\n<tr>\n<th>Weight<\/th>\n<td>approx. 18.5 kg<\/td>\n<\/tr>\n<tr><\/tr>\n<\/tbody>\n<\/table>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Allpowers SP037 400W Portable Solar Panel The ALLPOWERS SP037 is a foldable solar panel with a rated power of 400 W and a tolerance of \u00b15%, designed for charging portable power stations while camping, traveling in a RV, staying at a summer cottage, or in locations without access to the electrical grid.
