Hybrid solar inverter cost vs benefit calculation in Ghana

Can a solar PV/biogas/battery hybrid energy system provide electricity in Ghana?

This study analyses the prospect of utilising a solar PV/biogas/battery hybrid energy system to provide electricity for Ghana’s remote communities. The study goal is to utilise locally available renewable energy resources to achieve a cost-effective levelized cost of electricity (LCOE) and mitigate greenhouse gas emissions.

Do solar PV and biogas hybrid energy systems provide reliable and cost-effective electricity?

This study assesses the techno-economic viability of utilising a solar PV and biogas hybrid energy system to provide reliable and cost-effective electricity for Ghana’s remote communities. The study findings are relevant to decision-makers and policymakers towards increasing electricity access rates in remote communities in Ghana. 1. Introduction

How much power does a hybrid inverter use?

From the maximum power consumption of the air-conditioner (1.19 kW), the 2.0 kVA hybrid inverter with AC output of 1.6 kWac is appropriate for the air-conditioner used in this study. From the results of Fig. 5, it has generally been observed that humidity has more prominent effect on the power consumption of the air-conditioner than temperature.

Should Ghana adopt a PV/biogas/battery system for rural electrification?

In Ghana’s context, adopting a PV/biogas/battery system for rural electrification could contribute to Ghana’s agenda of saving about 11 million tonnes of CO 2 emissions by 2030 (Energy Commission, 2019).

How much electricity does a biogas system generate in Ghana?

PV modules and biogas gensets contribute 51% and 49%, respectively, of the annual electricity generated. The LCOE from the PV/biogas system is about 0.265 USD/kWh, which is relatively higher than the LCOE for Ghana’s household residents. Even with a 100% capital subsidy, the hybrid system’s LCOE is still high compared to the grid tariff.

What is a hybrid energy system?

The sporadic behaviour of certain energy sources has resulted in the evolution of hybrid systems. A hybrid renewable energy system (HRES) comprises more than one power generation technology, either renewable or conventional fuel units, that work in a standalone or grid-connected mode (Adaramola et al., 2014; Sinha & Chandel, 2014).
