What are the most effective solar system design strategies for existing structures?

We've trialled a vertical South facing wall with no shading and in winter with the sun low in the sky, it outperforms our roof system.

There are several strategies . Some of these strategies are: Integrating solar panels into the building envelope, such as the roof, windows, or fa?ades. This can reduce the need for additional mounting structures and materials, and provide power for direct current (DC) applications in buildings, such as LED lighting, computers, sensors, and motors. Applying passive solar solutions such as shading systems, reflective surfaces, thermal mass, natural ventilation, and daylighting. These can reduce the cooling and heating loads of the building, and enhance the comfort and well-being of the occupants.

Designing a solar system for a structure entails strategic placement and orientation of panels for optimal efficiency. Locating an area with ample, uninterrupted sunlight is key, steering clear of shading elements. The ideal orientation pivots on geographic location, advocating south-facing panels in the north and north-facing in the south. Tailoring panel tilt angles to mirror latitude or solar trajectory during seasons further enhances energy capture. Precision in these decisions maximizes solar absorption, fostering sustainability and amplifying the potential of renewable energy harnessing.

The strategy for the best effectiveness of Solar in existing structures is a project that has the best cost/benefit ratio, including the issue of (5) maintenance and monitoring. In terms of cost/benefit, it has the points of having a project with minimization of shadows, with a configuration that is as robust as possible to minimize replacements and maintenance. In addition, (6) the security issues of the facility and the people who access it are key items. It is not uncommon for us to find installations in houses/buildings where access to the roof is blocked. Poor design and with a compromised service life.

This varies highly depending on the country in perspective. If the country in question falls within the gulf then it would be best to utilize them within the shading of outdoor parking and connectivity to the main entrance. This works better than placing them on the roof as they are mostly utilized with MEP equipment. In addition, it is a municipality requirement to shade the pathways. However, the designer needs to account for the heat loss and allow an adequate height. This can be further utilized by passing the greywater/TSE around such structures as means of cooling down the panels to utilize them and filter the water at the same time.

A configura??o espacial de um sistema solar vai influenciar muito no seu licenciamento ambiental. Apesar de ser considerado uma tipologia de baixo impacto ambiental, em geral, se a área n?o for bem planejada os impactos poder?o ser mais significativos. áreas de mata e áreas de preserva??o permanente como nascentes, margens de rios e encostas muito íngremes e topos de morro n?o dever?o conter painéis para evitar a supress?o da mata nessas áreas. A mata nas áreas de preserva??o permanente possuem fun??es ecossistêmicas importantes na manuten??o do ciclo da água, regula??o do fluxo e ainda melhoram a qualidade das águas. Projeto bem planejado pode proporcionar impactos ambientais reduzidos.

Crafting a solar system involves key components: panels convert sunlight to DC electricity, an inverter transforms it to usable AC power, batteries store excess energy, and charge controllers manage the flow. Configuration hinges on energy goals, budget, and grid connection. Opt for a grid-tied setup for utility interaction, an off-grid system for autonomy, or a hybrid for flexibility. It's a tailored blend of tech and intent, where choices sculpt an energy infrastructure resonating with personal goals and environmental harmony.

Correcto, pero hay más opciones: .- De momento, las baterías son caras, lo que dificulta su amortización y supone un mayor desembolso inicial. Dependiendo de muchos factores, se podría aconsejar la contratación de una batería/hucha vertical que puede remunerar al consumidor los excedentes vertidos en red, lo que contribuye a un mayor ahorro/reducción del plazo de amortización

Panel Selection: Choose high-efficiency panels to get more power output per square foot, especially if space is limited. Consider the aesthetic impact on the building, selecting panels and mounting systems that blend with the structure’s design. Inverter Selection: Decide between string inverters, microinverters, or power optimizers based on the specific conditions of the site, such as shading or panel orientation variations. Mounting Systems: Use mounting systems appropriate for the roof type, ensuring they are durable and provide proper ventilation for the panels. Consider non-penetrative mounting systems for flat roofs to avoid leaks and preserve the roof’s integrity.

You can use PVWatts Calculator by the National Renewable Energy Laboratory or Project Sunroof by Google to calculate how much energy you can get from your panels based on your location.

Esto es cierto, pero dependerá mucho de las sombras colindantes y de la capacidad financiera disponible. También se ha de considerar los precios corrientes del mercado eléctrico, sus previsiones a futuro y, sobre todo, y tal y como he dicho antes, del patrón de consumo

Size the system based on the building’s energy consumption, roof space, and any future energy needs. Design the panel layout to maximize exposure to sunlight while considering shading from nearby structures or trees.

It's important the system is sized correctly taking into the customer consumption profile. A battery maybe needed in some cases.

Estoy de acuerdo, pero aconsejo dejarse asesorar por un experto en la materia, ya que se han de tener en cuenta muchas variables tales como las modalidades de contratación que ofrecen las empresas comercializadoras, el incremento en el valor del inmueble que supone contar con una instalación fotovoltaica, los gastos de mantenimiento, etc...

Creio que o principal Custo seria o wacc e por fim a TiR que o investidor determina para o projeto. Estas taxas de financiamento a princípio s?o determinantes quando falamos de projetos de 25anos por exemplo.

Depende de la ubicación de la instalación: en zonas urbanas yo aconsejaría proceder a la limpieza de los paneles 2 veces al a?o. En cambio, en entornos rurales con calles no asfaltadas la presencia de polvo aumentará considerablemente, por lo que sería deseable limpiezas más frecuentes. La presencia de aves también puede influir en la periodicidad del mantenimiento. En cualquier caso, lo que es absolutamente imprescindible es que el dise?o de la instalación tenga en cuenta las necesidades de mantenimiento, dejando pasillos lo suficientemente anchos para que los operarios puedan desarrollar su trabajo de una manera eficaz y segura

Los algoritmos se emplean para predecir patrones climáticos, revisar información de radiación solar, realizar simulaciones y optimizar el dise?o de los paneles solares para maximizar la captura de energía. La inteligencia artificial también ha sido útil en la gestión y el mantenimiento predictivo de sistemas solares, mediante el análisis de datos en tiempo real para identificar y prevenir posibles fallos o problemas de rendimiento, mejorando así la fiabilidad y la eficiencia general de los sistemas solares. Lo mas actual sería el desarrollo de algoritmos sofisticados para la optimización continua e integración inteligente de estos sistemas en redes eléctricas más amplias.

Include a monitoring system to track performance and identify issues early. Plan for easy access to the system for regular maintenance and cleaning.

Most home owners want all the features herein. And lifetime guarantee. Failure of a complex system is a big problem for homeowners, as is damage to roof structures not designed to support solar panels weight. Selling excess also must be guaranteed. Rule changes and company failure are unacceptable.

Implementing preventive maintenance and conducting annual inspections for a solar plant can significantly enhance its overall performance. Continuous monitoring enables the prompt identification and rectification of solar plant outages. Establishing an efficient feedback loop between the service team and design engineers can facilitate a shift towards optimized solutions for future plants.

No ano de 2022, houve um avan?o notável na capacidade de energia eólica e solar, registrando um aumento recorde de 266 GW. O setor solar em particular se destacou, contribuindo com 72% desse crescimento, equivalente a 192 GW adicionados globalmente. Um ponto crucial a se destacar é a lideran?a da China, contribuindo com a maior parte do crescimento na energia solar, representando 37% do total, solidificando sua posi??o como uma potência nesse setor. Entretanto, apesar desses avan?os promissores, desafios ainda persistem. Quest?es relacionadas à integra??o eficiente dessa fonte intermitente de energia, armazenamento e distribui??o continuam sendo áreas de foco para garantir a estabilidade e confiabilidade do sistema energético.

Working in industries that are very energy intensive, I've always been surprised that companies rather install PV systems, than heat collectors. Pharmaceutical industries use enormous amounts of steam: to generate the same energy with water collectors is approximately twice as efficient than generating electricity with photovoltaic cells. That's both in surface as in financial returns. The own usage of steam is always high enough to use the maximum. It could even be combined to sanitize the water...

A energia solar pode aumentar sua sustentabilidade com a chamada energia agrovoltaica ou agricultura agrivoltaica, que concilia a instala??o de painéis solares com planta??es específicas. Há diversas configura??es: instala??o de painéis verticais entre os cultivos ou pastagens; instala??o de painéis alternados com cultivos ; ou ainda a instala??o de painéis suspensos acima do cultivo. As culturas devem ser selecionadas de acordo com a necessidade de insola??o. Determinadas hortali?as ou frutas podem se beneficiar da incidência diminuída do sol. O consórcio contribui ainda pra diminuir a evapotranspira??o e o estresse hídrico das planta??es. Em agrovoltaicos existentes há registro de vantagens devido a menor temperatura abaixo dos painéis.

Integration with Existing Electrical Systems: Assess and, if necessary, upgrade the building’s electrical system to accommodate the solar system safely and efficiently. Plan for a seamless connection to the grid, with net metering if available. Regulatory Compliance and Incentives: Ensure the design complies with all local building codes, zoning laws, and utility requirements. Take advantage of any local, state, or federal incentives to offset the installation costs.

Algo adicional que no se comentó fue el tiempo de ejecución de los proyectos solares. Cuando un sistema es totalmente aislado de la red la instalación y puesta en marcha del sistema es muy rápida ya que no depende de otras empresas para que el sistema solar funcione. En cambio cuando los sistemas solares son interconectados a la Red en muchas ocasiones los proyectos que se instalan tiene una duración larga para poner en marcha el sistema por el trámite legal ante la operadora de red y las certificaciones pertinentes para que el cliente no tenga problemas a futuro con su sistema solar.
