JA Solar 545W Monocrystalline Solar Panel

JA Solar 545W Monocrystalline Solar Panel

The JA Solar 545W Monocrystalline Solar Panel is listed at 0.545kWp per module. Ten modules total 5.45kWp and twenty total 10.90kWp, providing a straightforward basis for comparing module quantities in a proposed solar installation. This page retains the existing 545W product view and removes the unrelated 465W gallery image. The complete JA Solar model remains to be confirmed, so the improved description distinguishes the known power class from electrical and mechanical details that still need the matching datasheet.

Correctly identifying the product in the gallery

The 545W listing previously included a gallery asset identified as 465W. It has been removed to reduce confusion between two different power classes. The remaining listing photograph is useful as a product view, but the exact module code must still be verified from the offered unit or supplier documents. The comparison illustration uses generic panel shapes and is not drawn to scale. It explains why the wattage and full model should be checked rather than relying on a similar appearance.

Array quantities for the 545W option

Six modules have a combined nameplate rating of 3.27kWp, ten have 5.45kWp, fourteen have 7.63kWp and twenty have 10.90kWp. Use those totals to compare a quotation with the intended equipment schedule. They do not state how many modules should be connected in a string. The inverter limits and the exact panel voltage and current data are needed for that decision. A module quantity is therefore a procurement and capacity reference, not a substitute for the electrical design.

545W and 465W are not interchangeable labels

At a quantity of ten, the two power classes total 5.45kWp and 4.65kWp respectively, a difference of 0.80kWp. That arithmetic explains why the wrong image label matters to a purchaser. It does not describe the performance of mixed modules or recommend upgrading an existing string by substitution. Dimensions, operating characteristics and the mounting requirements may all differ. Ask for full model verification whenever a product is being selected as a replacement or offered as an alternative to an original quotation.

Office-roof use as a planning example

An office building can have daytime electricity use that is worth considering when planning solar generation. The specific benefit depends on when equipment operates and how the complete system is arranged. The scene on this page is an application concept, not evidence of an installed project or a promised output. Compare your measured roof area and consumption schedule with the proposed array size. If evening or outage operation is required, those needs must be addressed by the separately specified inverter and storage system.

Comparing 545W with the 550W alternative

For ten modules, increasing the individual rating from 545W to 550W changes the nameplate total from 5.45kWp to 5.50kWp. The difference is only 50W across that count. Price, exact dimensions, documentation and compatibility may therefore be more useful comparison points than focusing exclusively on that small wattage difference. This does not imply that the two models have the same electrical specifications. A final choice requires the actual datasheets rather than assumptions based on adjacent catalogue ratings.

The electrical details required before connection

Request the full JA Solar code and its corresponding maximum-power voltage and current, open-circuit voltage, short-circuit current and temperature data. Those values allow the installer to assess the proposed configuration against the inverter. A power rating of 545W does not reveal whether a particular string will fall within the operating range or respect the input limits. Until the exact code is established, this page deliberately does not publish a guessed number of cells, current rating or maximum system voltage.

Understanding the two numerical charts

The capacity chart multiplies the selected number of panels by 0.545kW. The energy chart uses ten panels and a range of explicitly assumed equivalent full-power hours before losses. For example, four such hours give 21.80kWh by multiplication alone. Neither chart is a location-specific forecast or a battery-runtime estimate. The charts are included to make the product rating easier to interpret, while keeping the difference between panel power, daily energy and stored energy visible.

Mechanical checks before selecting stock

Obtain the length, width, frame thickness and mass for the model being supplied, especially where rails or roof positions are already fixed. Verify the installation requirements against that model documentation. The retained photograph cannot establish these dimensions, and a 545W label should not be used to assume compatibility with an existing JA Solar mounting layout. For a new installation, roof condition, access and the planned array arrangement need to be considered together rather than fitting panels into a photograph.

A more useful enquiry for Solar Deity

Include the quantity, delivery location and purpose of the purchase: new array, extension or replacement. Add the full inverter model and any existing module identification when relevant. Request the model-specific datasheet and applicable warranty documentation for the offered stock. If you are comparing the 545W and 550W options, ask for complete quotations with the quantities and equipment scope stated. That makes the comparison more meaningful than comparing a pair of pictures with similar panel designs.

Ordering scope and product documentation

The module listing does not imply that mounting equipment, batteries, an inverter or installation labour are included. Confirm those items separately if you require a complete solution. The product-view image, generated illustrations and calculated charts have distinct roles and are captioned accordingly. Efficiency, electrical ratings, dimensions and warranty duration remain subject to exact model confirmation. This keeps the description specific to the verified 545W offering without recreating the earlier confusion caused by the unrelated 465W gallery photograph.
