Photovoltaic + House

Problems

Inadequate and unstable power supply and high cost of self-consumption electricity are problems in some countries or regions.

Installation

The roof of a home usually has a free area, and solar panels are usually installed on the sunny side of the roof to get more full solar energy.

Solution

Building distributed PV systems in such cases can improve electricity security and power quality. Household photovoltaic has the characteristics of small installation capacity, many installation points, simple grid-connection process, and obvious and direct benefits, and is also a form of distributed photovoltaic power generation application with the highest state subsidy.

Photovoltaic + Commercial/Public/Factory Rooftop

Problems

High electricity consumption and high price of electricity. Most of these companies are large users of electricity. According to the characteristics of service industries such as commercial buildings, office buildings, hotels, conference centers and resorts, the user load characteristics are generally higher during the day and lower at night, which can better match the characteristics of PV power generation.

Installation

Municipalities and other public buildings, commercial rooftops, and private enterprises all have high-quality rooftop resources. Not only is the area large, but also the roof is flat, which is suitable for concentrated and continuous construction of distributed PV. Therefore, the installed capacity is large and the power generation capacity is also large. In addition, commercial buildings are mostly concrete roofs, which are more favorable for the installation of PV arrays.

Solution

These types of houses have long property rights and are more suitable for developing large rooftop power stations of megawatts or more. It not only solves the problem of electricity consumption for enterprises, but also makes a great contribution to the social and economic benefits of environmental protection. User loads and business practices are relatively reliable due to uniform management norms. Rooftop energy can be a potentially huge asset if used wisely. And from the investment point of view, commercial and industrial power plants are a better way to invest. Installing photovoltaic power plants on industrial and commercial rooftops can effectively revitalize fixed assets, save peak electricity costs, get a good return on investment, and at the same time reduce the internal temperature of the factory, promoting energy saving and emission reduction.

Photovoltaic + Farm/Fishery

Problems

Some of the areas are remote farming and herding areas far from the grid as well as coastal islands, which are often in the public grid not slightly, the power quality is poor.

Installation

1. Agro-photovoltaic complementary to the installation of solar modules on the roof of agricultural facilities to generate electricity, agricultural production under the shed to form a new power generation mode of "power generation on top and planting underneath".
2. Fishery and photovoltaic complementary refers to the combination of farming and photovoltaic power generation, installing photovoltaic modules on top of fish ponds, and farming aquatic products in the waters below the photovoltaic modules, forming a new power generation mode of "power generation on top and fish farming underneath".

Solution

Off-grid PV systems or micro-grid power generation systems complementary to other energy sources are well suited for application in these areas. It maximizes the use of land resources, increases ecological and social benefits, improves farmers' income, and effectively drives local economic development.
