Solar ground screw anchor also called ground screw or earth screw It has the following benefits:
Easy installation: One solar ground screw can easily be hit into the soil deeply by a hydraulic driver within 1 minute, no need dig or soil removal, no need concrete base, no need long time of reinforce of the wet cement. Immediately ready for loading.
High stability: Solar earth screw made with spiral blade to designed having excellent quality of pull-out resistance and high stability, which provide an ideal solution for solar mounting system even under fast wind and heavy snow load, kind of harsh weather condition.
Multi-function: steel ground screw adapted to many kinds of soil foundation: gravel, sand and clay, it meets the requirements of any solar projects fay beyond.
Durability: earth screw for solar made of good quality steel with hot-dip galvanizing surface treatment to reach the effect of long term anti corrosion performance, it will last 20-30 years usage.
Cost effective: solar ground screw anchor save money and time greatly comparing to the concrete base! It can be loaded at once and capable of using less materials.

Solar ground screw anchor is a widely used anchor base for supporting the mounting system for PV modules. It is a steel tube wielded with spiral blades that piled into deep into soil and achieve a firm foundation for solar racking system.
The best strong points of earth screw is its high stability and high pullout resistance. The wide blades area ensure its holding power, so it suits well among the districts where suffering from strong wind and heavy snow. Best performance in the very dense soil, ideal for rock.
As a matter of fact, earth screw can be installed everywhere, clay, sand, gravel. It is very easy to be piled into soil with a driver. It is fast and economic comparing concrete foundations. It also save time! It save a lot of time especially on the area where labor fee is high.
Alv's solar ground screw anchor made of high quality steel treated with professional hot-dip galvanizing craftsmanship. The usage life can extend to 30 years or more.
In a summary, alv's solar earth screw provide you a reliable and low cost solution for solar mounting. It is easy, stable and durable. The screws can be reused and it is recyclable.
Alv has a strict production and quality control system, here a simple procedures of production:
1 How to install a solar ground screw?
Solar earth screw can be installed by a portable or a hydraulic pile driver by pressing the screw into the soil by constant heavy bums , usually 1.5 meters deep is enough for strong and stable solar mounting base, some up to 1.6m depth. After that, build the mounting system of pv modules on the tops of earth screws with some base connectors.
2 What are the advantage of solar ground screw?
Compare to the other supports for solar mounting system(concrete eg.), it provide several premium advantages: easy installation, cost effective, high efficiency, and easy to dismantle .
3 What kinds of ground suite for solar earth screw?
It suitable to clay, sand and gravel. The ground soil must be strong enough to support the panels and withstand the strongest wind and heaviest snow.
4 Does this screw suitable for the area of fast wind and heavy snow?
Yes, It can bear to design limitation up to 60m/s wind and 14 KN/m2 snow load.
5 How long will the solar ground screw mounting system last?
It is durable and strong. The usage life up to 30 years or more. But it may differs depend on the characters of the soil and weather conditions.
6 Is the solar ground screw reusable ?
Yes. It can re used if the screws does not damaged after removal. So please be careful when dispatching the screws on site. This reused feature make the mounting system by ground screws sustainable.
