Off-grid solar power generation system is an off-grid power generation system that converts sunlight into electric energy and stores it in batteries.TUNTO is favored because it can provide basic household electricity in areas where electricity is unstable and difficult to deliver, and the power generation equipment must be able to withstand harsh operating conditions.


TUNTO Greenpower is a professional solution design and solution provider. We are involved in product design, production and system design of photovoltaic products.

Customers from all over the world put forward their requirements, and we try every means to assist them and realize their ideas

Can work 24 hours a day; Solar panels that meet US quality standards are available to customers.


With word of mouth advertising all over the world, we have built reputation in solar energy industry. It is the attitude of TUNTO employees to make friends with customers and make Suggestions for the business based on the principle of win-win. Over 10 years of cooperation, we have established a stable and cooperative relationship with customers, which is the main reason for the stable sales of TUNTO products in various countries


The lamps we purchased from TUNTO in the past 6 years are still in normal use.They have come to China again to place new orders. Time is the most authentic evidence to verify the quality of the products.


After three years of cooperation, these products have been sold very well in our market. The classic models have formed a stable demand, and the new models from time to time can always surprise the market and increase our market share.


Equipment purchased for the project has few problems and little human maintenance costs over a three-year period. Tunto is more worthy of long-term cooperation than other previous suppliers.


Compared with many of its peers, TUNTO's plant is relatively larger, with better production processes and environment. TUNTO has more than 10 years of experience in this industry, they are professional and have helped me avoid many of the problems that would have arisen.


Located in Guangzhou, Tunto Green Power Technology Co.,Ltd (Simplified as “ Tunto Green Power”) was established in 2012, it is a Chinese national Hi-tech enterprise which is specialized in developing renewable energy and smart electricity storage and conservation devices.


With the mission of “Sunshine changes life and technology changes the world”, we are having been sparing no efforts to move the solar energy into electricity application and we have grown to be off grid solar system and solar electricity solution integrated company.

Solar tech: what’s new in 2018?
There are two main types of solar technology: photovoltaics (PV) and concentrated solar power (CSP). Solar PV technology captures sunlight to generate electric power, and CSP harnesses the sun’s heat and uses it to generate thermal energy that powers heaters or turbines. With these two forms of solar energy comes a wide range of opportunities for technical innovation. Here are some of the latest emerging solar panel technologies for 2018:
India's PV installation capacity plan was derailed by tariff increases
India's imports of solar cells fell to $1.4 billion (1.25 billion euros) between April 2019 and November 2019. Imports of solar cells were $2.15 billion in fy2018/2019, compared with us $3.83 billion in the same period last year. But this decline has led directly to a decline in new solar capacity in India.
