Off-grid solar systems using PAYG models

The combination off-grid solar systems and pay-as-you-go models of payment is an approach used in many developing countries to alleviate energy poverty, especially in rural areas.

Pay-As-You-Go (PAYG) is a popular model of financing for off-grid solar systems. It allows consumers to pay only for the electricity service they use through a simple and convenient process, without requiring them to have a large initial sum of money or pay high deposits or monthly fees. In this way, PAYG systems are very affordable and inclusive.

In addition, off-grid solar technology can be used as an alternative source of energy for both businesses and homes who cannot rely entirely on the national grid because it is often unreliable and expensive, or simply that it not available at all. The PAYG approach, therefore, works well in these cases because it does not require any significant investment from either the consumer or utility provider – which makes it an attractive, cost-effective way to deliver electricity services to the 11% of the world’s population who are without reliable access to electricity.

Off-grid solar systems are typically used in individual homes or small businesses where there is no other source of lighting and power. It can also be used as an “extension” for households that already have some kind of access to grid power but do not have enough to meet their demand.

When using PAYG financing for an off-grid solar system, it is important to determine what financial model should be used before implementation starts – because all three main models (lump sum payment, pay to per use, and prepayment) each involve different processes and result in different costs for customers at different levels of consumption. Thus, it is important to take into account what type of customers are being targeted in terms of energy use when determining the financial model that should be used.

The following considerations must also be taken into account when implementing PAYG systems:

– The customer’s creditworthiness and ability to pay on time;

– The level of trust between utility provider and end-user;

– The number of products (and combinations of products) that will be offered;

– The willingness of people to make long term contracts;

– How many prepayment points there will need to be in place for start-up costs.

For instance, if a household has access to electricity through another service microgeneration or grid extension but is unable to make enough money for regular payment of bills, an off-grid solar system will be an alternative. However, after some time, the family may run out of money and require more credit to keep up with monthly bill payments. If this is the case, one must consider whether the customer would be willing or able to take on larger loans or increase their debts in order to pay for their energy services.

Pay as you go (PAYG) financing for off-grid solar systems have been shown in many countries to be effective in improving people’s livelihoods by giving them access to electricity – but it does require careful consideration when setting up each project so that it works best for both utility provider and customer.

An example company using PAYG solar system in Kenya for an off-grid solar system is M-KOPA, which offers a simple pay-as-you-go plan using solar home systems to provide reliable electricity access. This includes an inbuilt SIM card so that customers can top-up credits when they are running low without the need for any additional hardware or accessories.

Another example company in Tanzania in East Africa is Off-Grid Electric (OGE) – who not only use PAYG financing but also have future plans to integrate their technology with mobile money payment methods such as M-PESA to further enhance convenience and ease of accessibility for both utility provider and customer alike.

The Solar Home System (SHS) used by these two companies are well suited because it can be installed above ground and is not dependent on surrounding environmental conditions such as shade or water availability, which makes it a viable option in areas where wiring infrastructure is difficult to install.

In addition, this system will be able to determine the amount of solar power needed to fulfill a customer based on their past usage history and current credit balance, allowing it to accurately track different types of consumption while also making sure that customers have enough money in their account. This means that if there is a sudden increase in demand for power – such as a larger family moving into a house or an influx of new customers – the system will be capable of handling these changes without any major disruptions to service.

However, one shortcoming is that the benefits of sustainability cannot be guaranteed, due to possible default from customers who are unable or unwilling to pay for their electricity. In order for companies

There are different payment options for off-grid solar systems, including pay as you go (PAYG), hire purchase, post-paid or other forms of credit.

These types of solar lamps can be found for example in many rural regions in Kenya where the majority of the population cannot afford the initial cost. The PAYG option provides customers with no upfront costs and low monthly payments to help meet their energy needs. It is suitable for customers that do not have access to bank accounts or who cannot make an advance payment for a solar home system. With this system, it is possible to install a basic solar lighting system within one day at affordable capital cost and incremental operating cost over time (on average around US$ 7/month).

Pay-as-you-go (PAYG)

Pay-as-you-go (PAYG) is an approach that provides energy services to customers by enabling them to pay only for the energy they use. Using PAYG, innovations in a renewable distributed generation are combined with intelligent information and communication technologies for off-grid solar systems. The PAYG model allows users to access affordable ‘pay as you go’ basic electricity services using cheap local technology, without any upfront costs. This type of payment method can be found in rural regions where families do not have access to bank accounts or cannot make advance payments for a home system. Customers receive instant financing at their doorstep under this service that enables them to go “off-grid” within one day on average with a basic lighting system at affordable capital costs and incremental operating cost over time.

The PAYG model allows customers to pay only for the energy they use, typically at a rate of US$ 0.5 per kWh. Customers make a small down payment on their solar home system and then buy pre-paid cards from local retailers that give them access to electricity by paying for units of energy as they use it from their solar home system. They can top up their accounts with either scratch cards available from retailers or using mobile phone payments. The average monthly bill ranges from US$ 9 to US$ 18 depending on usage and location.

In regions where power supply is unreliable, expensive, or absent, off-grid systems combined with PAYG offer a compelling alternative for rural electrification. This is especially true in sub-Saharan Africa where most people are not connected to the grid and rely on kerosene lamps for light at night, candles or open fires for cooking, and wood stoves for heating.

Pay as you go solar systems can play a crucial role in injecting new energy into the development of off-grid markets, providing consumers with an affordable, scalable energy access solution.

PAYG’s key advantage compared to many other clean energy products is that it allows customers to purchase only what they need when they need it. PAYG systems are often more cost-effective than other forms of lighting, such as rechargeable solar lanterns because they provide steady all night long, lessening the need to recharge.

PAYG solar systems provide benefits such as more energy security, lower energy costs, more efficient use of lighting, and phone charging – which can help households increase income through more productive time for work or study. PAYG solar home systems are also very easy to manage with some customers reporting making payments in just 10 seconds with their mobile phones.

Off-grid lighting is often the first step on the energy ladder that leads people to recognize the value proposition of modern energy services and provides a sustainable customer acquisition channel for product developers and distributors alike.

What is an off-grid solar system?

Off-grid solar systems are small, self-contained photovoltaic (PV) systems that provide electricity to small businesses and homes not connected to an electrical grid. The artificial lighting provided by off-grid PV systems can save money for families who previously used kerosene lamps or candles; the system allows people to work more hours each day, increasing income; students can study at night; refrigerators enable modern medical practices; phone charging provides access to telecommunications.

PAYG’s key advantage compared to other clean energy products is that it allows customers to purchase only what they need when they need it. PAYG solar systems are often more cost-effective than other forms of lighting, such as rechargeable solar lanterns because they provide steady all night long, lessening the need for a recharge.

What are the benefits of pay as you go?

With PAYG systems, users purchase pre-paid cards from local retailers that give them access to electricity, typically for a rate of US$0.5 per kWh. Customers make a small down payment on their solar home systems and then buy the pre-paid cards from local retailers that give them access to electricity by paying for units of energy as needed.

The flexibility offered by this method benefits not just consumers—because it reduces the risk of theft and eliminates the need for renters to ask landlords’ permission before installing renewable technologies—but also retailers because it creates new business opportunities through increased footfall in rural areas where shops are often low on stock or adjacent to high street locations that attract many passersby. Because they provide all-night light, PAYG solar home systems are often more cost-effective than other forms of lighting, such as rechargeable solar lanterns.

Therefore, PAYG is particularly suited to customers that use fuel sources based on combustion (such as kerosene lamps or candles) because it typically costs less per kWh. The flexibility offered by this method benefits not just consumers—because it reduces the risk of theft and eliminates the need for renters to ask landlords’ permission before installing renewable technologies—but also retailers because it creates new business opportunities through increased footfall in rural areas where shops are often low on stock or adjacent to high street locations that attract many passersby.

Further savings are achieved when customers purchase larger systems because the initial down payment covers a significant portion of the total cost.

Off-grid lighting is often the first step on an energy ladder that leads people to recognize the value proposition of modern energy services and provides a sustainable customer acquisition channel for product developers and distributors alike.

The one major drawback with pay-as-you-go technology is that it requires users to make regular payments to be able to use the system, so it is less suitable for customers with irregular incomes.

Another key benefit of pay-as-you-go technology is that it requires users to make regular small payments in order to be able to use a system. This makes the product more difficult for customers who have erratic income levels. It also means that users are less likely to default on their loans because they have already paid off part of the financial commitment prior to installation. For this reason, PAYG systems are often seen as a sustainable option for rural dwellers without access to reliable electricity, but they require an initial investment by the user and so are not always suitable for low-income households.

PAYG technology enables users to purchase access to modern energy services on a pay-as-you-go basis, making it ideal for customers with erratic income levels. PAYG also eliminates the need for renters to ask landlords’ permission before installing systems and reduces the risk of theft.

While PAYG solar home systems often cost US$10–20 more than other forms of lighting such as lanterns, they provide steady all night long, lessening the need for a recharge, so they are often more cost-effective overall. The flexibility offered by this method benefits not just consumers—because it reduces the risk of theft and eliminates the need for renters to ask landlords’ permission before installing renewable technologies—but also retailers because it creates new business opportunities through increased footfall in rural areas where shops are often low on stock or adjacent to high street locations that attract many passersby. Further savings are achieved when customers purchase larger systems because the initial down payment covers a significant portion of the total cost.

In conclusion, pay-as-you-go technology enables people to purchase access to modern energy services on an ad hoc basis, making it ideal for customers with erratic income levels. It also eliminates the need for renters to ask landlords’ permission before installing systems and reduces the risk of theft.
