How Agri-Photovoltaics (Agri-PV) Successfully Combines Agriculture and Energy Production — A How-to Guide

5 min read

Agri-pho­to­voltaics, also known as Agri-PV, is an inno­v­a­tive con­cept that com­bats cli­mate change while pro­mot­ing a sus­tain­able ener­gy future. This com­pre­hen­sive how-to guide explains how Agri-PV works, how it is used, and what ben­e­fits it offers to farm­ers and ener­gy pro­duc­ers alike. Agri-PV projects are par­tic­u­lar­ly attrac­tive for farm­ers with arable land, grass­land, and agri­cul­tur­al land with per­ma­nent or mul­ti-year crops.

Introduction: What is Agri-Photovoltaics?

Agri-PV is a tech­nol­o­gy that allows the simul­ta­ne­ous use of agri­cul­tur­al land for both food pro­duc­tion and solar pow­er gen­er­a­tion.

Main Benefits of Agri-PV

• Attrac­tive Invest­ments through Sub­si­dies: Fixed feed-in tar­iff over 20 years of up to 9.5 ct/kWh.
• Effi­cient Land Use: Pro­duce ener­gy and food on the same land.
• Pro­tec­tion of Crops: Pho­to­volta­ic sys­tems pro­vide pro­tec­tion against exces­sive sun­light, hail, or wind.
• Diver­si­fied Income Streams: Addi­tion­al income through the feed-in of solar pow­er into the grid.

How to Successfully Implement Agri-PV: A Step-by-Step Plan

1. Site Analysis and Land Selection

The first step in suc­cess­ful­ly imple­ment­ing Agri-PV is site analy­sis. Both the cli­mat­ic con­di­tions and the geo­log­i­cal char­ac­ter­is­tics of the agri­cul­tur­al land must be con­sid­ered. It is impor­tant to select a site that pro­vides enough sun­light while not neg­a­tive­ly affect­ing agri­cul­tur­al pro­duc­tiv­i­ty. It is also cru­cial to con­sid­er the priv­i­leged sta­tus of land for the instal­la­tion of Agri-PV sys­tems, which allows for a faster approval process through local munic­i­pal­i­ties.

Key Factors in Site Analysis:

• Solar Radi­a­tion: The solar pan­els should gen­er­ate enough ener­gy to be eco­nom­i­cal­ly viable.
• Soil Qual­i­ty and Crops: The inter­play between solar pan­els and plants requires a care­ful analy­sis of soil prop­er­ties and the crops grown.

2. Planning the Solar Modules: Design and Orientation

The next step is the plan­ning and design of the Agri-PV sys­tem. The design plays a cru­cial role in ensur­ing that agri­cul­tur­al activ­i­ties are min­i­mal­ly impact­ed or even enhanced.

• Height and Spac­ing of Mod­ule Rows: The mod­ule rows must be posi­tioned to pro­vide enough space for the use of agri­cul­tur­al machin­ery.
• Ori­en­ta­tion and Tilt: To achieve opti­mal sun­light expo­sure while pro­vid­ing shade for crops, the mod­ules should be installed at an appro­pri­ate angle. Ylek­tra uses so-called “track­ers” that allow the mod­ules to tilt with the sun, ensur­ing opti­mal align­ment at all times. This can increase yields by up to 50% com­pared to fixed PV sys­tems.

3. Permits and Regulatory Requirements

Agri-PV projects are sub­ject to numer­ous reg­u­la­to­ry require­ments. In Ger­many, agri­cul­tur­al busi­ness­es must ensure that all nec­es­sary per­mits are obtained before start­ing instal­la­tion. Addi­tion­al­ly, com­pli­ance with DIN SPEC 91434 is required to receive fund­ing for 20 years as an Agri-PV oper­a­tor.

• Con­struc­tion and Oper­at­ing Per­mits: These vary depend­ing on the fed­er­al state.
• Grid Con­nec­tion: Ensur­ing that the gen­er­at­ed elec­tric­i­ty can be fed into the pub­lic grid is anoth­er chal­lenge.

A help­ful link for reg­u­la­to­ry infor­ma­tion in Ger­many is the Bun­desnet­za­gen­tur web­site. It is also advis­able to involve exter­nal part­ners in the project plan­ning and approval process­es to ensure that all require­ments are met.

4. Installation and Construction

The instal­la­tion of Agri-PV requires col­lab­o­ra­tion with pro­fes­sion­als in the renew­able ener­gy sec­tor. Com­pa­nies like Ylek­tra GmbH pro­vide sup­port in plan­ning and imple­men­ta­tion.

• Pro­fes­sion­al Instal­la­tion: The instal­la­tion should be car­ried out by cer­ti­fied tech­ni­cians to ensure safe­ty and effi­cien­cy.
• Option­al Com­bi­na­tion with Bat­tery Stor­age: Inte­grat­ing bat­tery ener­gy stor­age sys­tems (BESS) allows the ener­gy pro­duced to be used even when the sun is not shin­ing. Learn more about bat­tery stor­age at Ylek­tra Bat­tery Stor­age.

5. Operation, Maintenance, and Optimization

The long-term suc­cess of Agri-PV also depends on reg­u­lar main­te­nance. Since both agri­cul­tur­al and tech­ni­cal com­po­nents are involved, main­te­nance can be chal­leng­ing.

• Clean­ing the Mod­ules: Dust and dirt can reduce the effi­cien­cy of the mod­ules. Reg­u­lar clean­ing is essen­tial.
• Mon­i­tor­ing Sys­tems: Using dig­i­tal mon­i­tor­ing sys­tems can help con­tin­u­ous­ly track and opti­mize the sys­tem’s effi­cien­cy.

Frequently Asked Questions (FAQ) about Agri-Photovoltaics

• How large is an Agri-PV sys­tem, and how much land is required? Agri-PV sys­tems with a capac­i­ty of up to 1 MW, installed near farms, are rel­a­tive­ly easy to imple­ment and require an area between 1 ha and 2.5 ha, depend­ing on the mod­ule rows. Agri­cul­ture con­tin­ues between the mod­ule rows.
• How much income can I gen­er­ate with Agri-PV? This depends on the loca­tion, size, and oth­er con­di­tions. How­ev­er, you can expect sig­nif­i­cant­ly high­er income com­pared to just agri­cul­tur­al use of the land.
• What are the costs for Agri-PV? The costs vary depend­ing on the size of the project and spe­cif­ic require­ments, but there are numer­ous sub­si­dies and investors that make entry eas­i­er.
• How do crops ben­e­fit from Agri-PV? The PV mod­ules pro­vide pro­tec­tion from exces­sive sun­light, improv­ing the micro­cli­mate.
• Can Agri-PV be used in any cli­mate? Agri-PV is par­tic­u­lar­ly suit­able for regions with high solar radi­a­tion but can be used in almost any loca­tion.
