50W
For a plot of 300 square meters, 50W is enough if it is 20 meters. The lamps are electric lamps which are converted into electrical energy by solar panels. During the day, even on cloudy days, this solar generator (solar panel) can collect and store solar energy. As a new safe and environmentally friendly electric lamp, solar lights are receiving more and more attention.
How to choose the power of solar garden lights? What is the appropriate installation height?
Is it good to install solar lights in a personal yard? The question of whether it is recommended to install solar lights in a personal yard should be considered from three aspects.
First of all, whether it is good or not to install solar lights in the yard, you can consider the following aspects: Does the yard need a solar light?basic airing or decorative lighting?
Basic lighting means that it needs to illuminate a road or passage, etc., and it is used every day, and it cannot be used without lighting. If you have such lighting needs, it is better to use commercial lights rather than solar energy, because the disadvantage of solar energy is that if the weather is cloudy for several consecutive days, it will be at short of energy. The path or passage in the yard is dark and dangerous without light. If it's just decorative lighting, for example, I hope the light can be on at any time, but can be turned off for a few days without affecting my normal activities in the yard. In this case, the use of solar energy can still be used. to be considered.

Then if sunlight in the areainstallation is sufficient. If you choose solar energy, you need to consider whether there is enough sunlight to charge the solar light during the day. For example, in areas like Guangdong, where short-sleeved clothing is worn almost all year round in summer, there is almost no reason to hesitate when using solar energy. However, in some areas the days are often cloudy and rainy, and if there is insufficient sunshine, you need to think carefully.
Finally, is the quality of solar lights good? The quality of solar lights on the market now varies. For the same light, some people claim 80 W and others 120 W, but this is not the real power. Therefore, you should not focus on this data when purchasing. This does not mean that the higher the power, the greater the brightness. When purchasing, you should pay attention to the lightnosity and duration and choose a reliable brand manufacturer to buy.
Garden lights generally do not need to be too bright, as long as they meet basic lighting requirements and allow people and objects on the road to be seen. It is too light and interferes with residents' rest in the middle of the night.
At present, these are mainly LED lamps, energy efficient and with high brightness. Generally, the power does not exceed 30W, which is determined according to the style of the garden lamp.
The total height of garden lights is generally 3.5 to 4 meters.
