What Customer say
These solar panels are the most advanced, sturdy, durable, and efficient panels. They are worth paying every penny. What I bought is a residential off-grid solar system, and the system works very well during use. I purchased all the components including modules, batteries, brackets, inverters, and so on from Sunpal. So far, I am very satisfied with this solar system and accessories. So far, my solar panels have not had any problems. Good product, highly recommended.

These are a little on the heavy side, however that is probably because they are very sturdy and very well built. They provide continuous satisfactory output even with overcast days. Fast shipping and professional service, the box arrived in good condition. There were no smudges on the surface, I'm very happy with the quality.

I ordered 2*40 feeds solar panels 1270 PCs and they arrived in good condition. Once tested I was happy with the output that was higher than another brand panel that I bought another solar module factory in China. I am in a northern state of America and the sun is always less than directly overhead. These panels when connected 2 in series to a inverter are outputting near their rating for about 3+ hours per day and are above 60% of their rated output for more than 6 hours per day. Because I was happy with the first order, now Sunpal is the only solar panel supplier,  I will be ordering additional panels from them.

    30% off! US extends PV investment tax to 2032
    According to foreign media reports, U.S. Senator Joe Manchin and Democrats have reached an agreement on a settlement bill, which is called the "Reducing Inflation Act of 2022". The bill includes $370 billion in spending on renewable energy and climate measures, a surprise victory for the photovoltaics and cleantech industries. One of the most influential provisions of the act is the long-term extension of the investment tax credit, which has played an important role in the development of the U.S. photovoltaic industry. The bill calls for a 10-year extension of the 30 percent investment tax credit available for PV systems, before gradually dropping to 26 percent by 2033 and 22 percent by 2034. The tax credit applies to entities and individuals that employ photovoltaic technology. In addition, the 30% investment tax credit also applies to energy storage systems, whether co-located or independently deployed. One measure the industry hopes the U.S. government will take is a "refundability" clause, but that measure isn't in the bill. Refundability means that if the tax credit is worth more than the tax owed for the year, it will be paid out as a cash refund. This provision is not included, which hinders the credit worthiness of certain individuals, however the tax credit can be deferred to the next year. There are also several "additions" to tax credits, depending on the type of organization, domestic product use, and project location. For some projects, investment tax credits can be as high as 50%, according to ROTH Capital Partners. The credit also includes a "direct payment" provision. This will allow PV developers with little or no tax liability to treat the credit amount as an overpayment of tax, and they will receive a cash refund. Abigail Ross Hopper, president of the American Photovoltaic Industry Association, said: "With long-term incentives for the deployment and manufacture of clean energy generation facilities, the U.S. photovoltaic and energy storage industries will create hundreds of thousands of new jobs and start building American energy. The next era of leadership. This is a critical opportunity we cannot afford to miss, and now the U.S. Congress must reach a deal and pass this legislation.” The bill is expected to go to the U.S. Senate for a vote as early as next week.

    India's New Deal: Allows developers to import components at a 5% discount to avoid basic tariffs
    Recently, the Advance Ruling Bureau of Indian Customs allowed the import of all components of solar projects at a preferential tax rate of 5%, thus circumventing the basic duty. To facilitate local manufacturing of solar cells and modules, the Indian government has introduced several tariff barriers such as a safeguard duty of 25%-15% effective July 2018-July 2021 and effective April 1, 2022 , 40% basic duty (BCD). These tariffs have increased the cost of solar projects across India, forcing developers to seek cost-saving ways to bypass them. However, in a recent petition, Aquila Solar Power (Vibrant Energy Holdings), a Telangana-based solar project developer, asked the authorities to consider allowing it to import all components of the project at a preferential tax rate of 5%. Modules are the most prominent cost element of solar power projects, accounting for more than half of the overall project capital expenditure (CAPEX). The authorities' decision contradicts the Indian government's indigenous policy of promoting solar module manufacturing.
