Paint the bottom of the photovoltaic panel white
A white surface will scatter the light, and unless its really close to the target, not much will reach the solar panel but diffuse away in all directions. You could just try reflecting the sun's image onto a nearby wall. First with a mirror, and then with a white surface.

FAQs about DC measurement of energy storage system
What is a DC energy meter?
The DC energy meter is an instrument designed for applications such as DC panels, solar power supply, telecommunications base stations, DC charging station, and battery energy storage systems. It can measure the voltage, current, power, and forward and reverse energy in the DC system. The following is a detailed analysis of the DC energy meter:
Can DC metering be used in electric vehicle charging stations?
In this article, opportunities for dc metering in electric vehicle charging stations, renewable energy generation, server farms, microgrids, and peer-to-peer energy sharing will be discussed, and a dc energy meter design will be proposed.
What is a rail-type DC energy meter?
In container-type lithium battery energy storage systems, rail-type DC energy meters are particularly widely used because they are easy to install and can provide forward and reverse, 1-2-way energy metering and basic communication interfaces to meet the energy metering and monitoring needs of energy storage cabinets.
How to measure DC current?
Electric current can be measured either by direct connection or indirectly, by sensing the magnetic field generated by the flow of the charge carrier. The next section will discuss the most popular sensors for dc current measurement. Direct connection current sensing is a tried and tested method of measuring ac and dc current.
Do EV chargers need a DC energy meter?
In order to fulfill the measurement requirement, dc energy meters for EV chargers may be required to have multiple voltage channels, enabling the meter to sense the voltage also at the entry point of the vehicle (4-wire measurement).
How much power does a rack use?
A typical modern rack consumes up to 40 kW of dc power. Therefore, currents up to 100 A are required to be monitored with billing-grade dc meters. In the early 1900s traditional ac energy meters were entirely electromechanical. The combination of a voltage and a current coil was used to induce eddy currents in a rotating aluminium disc.
